P: Generative Remove Feedback (Lr Classic & Lr Eco)

@Photos by Bre: "Now I get ghosting or a complete replace with a similar object."

1. The red dot under the Masking button indicates you've applied Remove on top of an AI mask, which can cause ghosting. Do the menu command Settings > Update AI Settings, or apply Remove before masking.

2. The replaced section of the white pole in your screenshot indicates you had Mode: Remove selected with Detect Objects checked.  Detect Objects doesn't do well at detecting long lines and poles -- uncheck Detect Objects and try it again.

If this doesn't help, please attach a full-resolution JPEG exported from the unmodified original photo, so we and Adobe can see the issue in detail. With nearly everyone who has posted a problem photo, we've been able to show how to quickly remove the desired objects.

@LivPhoto: "I'm trying to remove powerlines and it's replacing it with more powerlines?"

@Wilbur16B8: "Far too often, rather than simply removing the offending object, the remove tool simply substitutes another offending object."

@quinet2000: "I have a dual monitor set up. When I select an object to remove on my main screen, it shows up in red off-centre by about a centimeter."

Please submit a bug report about this:

https://community.adobe.com/t5/lightroom-classic-bugs/how-do-i-write-a-bug-report/idi-p/12386373 

which will make it more likely Adobe will set it and respond. Be sure to include screenshots (or better, a full-resolution screen recordings) and copy/paste the entire output from the menu command Help > System Info.

@johngregoryfcb: "Is there a way to select the mask to be used with Generative Remove the same way you select normal masks? For example detecting people, parts of people, subject, sky."

No. You could submit a feature request here:

@DhandaNot your screenshot shows you need to Update Ai Settings for Masking i.e. Red Dot under Masking panel icon.

If you have a Sky Mask apllied it might be the cause of the smudges.

Consider also there is a bug when trying to clone/heal a Sky affected by ANY type of Masks.

@Patrick22616748c1sx: "almost always it replaces the object it's supposed to remove, with a similar object. Want to remove a straight street lantern from an image? Here's a weird looking street lantern in a different style"

@Jasminder Singh_Obero8336: "In the latest update in Lightroom Classic on Generative Remove Tool, it just refuses to remove faces. As alternates it keeps giving new faces"

Your screenshot shows there are two causes, both related to the general principle that you have to select all of the object you want to replace -- if you leave any bits remaining, Remove will try to match the remaining parts:

1. You didn't select all of the person's arm.

2. You have to select all the disconnected pieces of a person. Your screenshot is ambiguous, but it looks like you tried to include the lower body of the person. The screenshot doesn't show if you selected every bit of that person.

There's also a UI design misfeature that Adobe hasn't acknowledged as such. Though Adobe tells you to select all of the disconnected parts of the object, if you make disconnected selections, Remove will treat them separately when it goes to remove, and you're likely to get "replace" instread of "remove".  So you need to apply an obscure trick (described in more detail here).

First select all of the bits of the person with a single selection (making sure Detect Objects is unchecked):

Then before clicking Remove, use Subtract to delete the parts of the selection you don't want removed:

Then click Remove:

It's too bad that Remove still has such rough edges. Once you learn about its quirks, it does a very good job, quickly.
