All proof settings remain checked

This problem has actually been around for a while. I believe I reported it to Adobe a while ago. It’s very easy for me to reproduce it on macOS in seconds, see below. This is in Photoshop 27.7 on macOS 26.5, but I’ve seen this problem across multiple recent versions of Photoshop and macOS, on two different Macs. 

Example 1: Proof Setup

Just like michaljanata says, if I choose another Proof Setup, the first remains indicated as selected, so it looks like multiple proof setups are selected, which is not possible. The only way to understand which proof setup is actually active is to look somewhere else in the UI, such as in the document tab.

Example 2: Free Transform

After making a selection, the command Menu > Free Transform starts out unselected. After I choose that command to start a transformation, the command is marked in the menu as selected, as expected. I then cancel the transformation, and you can clearly see that Free Transform is no longer active in the options bar or on the canvas. But when I click the Edit menu…Free Transform says it’s selected! 

There may be other examples, but those are the two that immediately come to mind. Since this problem started, the misleading UI feedback makes it more difficult to understand the current state of the Photoshop features it affects.

That is not normal. I’ve tried here (v27.6 and Windows 11) and I cannot get more than one to be checked. I would try resetting preferences (back them up first so you can restore them if it does not solve the issue).
