Cloning Tool does not seem to be working

[PinholeR5]

I'm having trouble wiht the Cloning Tool in Lightroom Classic.  It does not seem to work.  I've used it thousands of time with no issues, but somehow it isn't working.  I try to clone an area but the target area remains unchanged.  

I'm up to date with the latest version running on Windows 11.

It is really strange.  I moved the source to include the fence, and with 0 feather. It does substitute it in but the dot I'm trying to remove is still there!   Now, the dot itself is in the image and not the monitor because I can move the LR window around and the dot stays in the same place in the image.

Do you have a background mask? I would expect this if you have created a background mask and adjusted it, then tried to remove a spot with any of the CA Remove/Heal/Clone modes. If you do have a background mask, select it in the Masking panel and it may be showing a warning that AI Settings Update is needed.

Yes! Thank you for the suggestion. That solved my issue.

It wasn't a background mask but a stray mark from an adjustment mask I had made with the brush to deal with some blown-out highlights.  I must have inadvertently clicked while moving the mouse, leaving a stray dot.
