Remove object is adding random unknown people to my photo! It worked this morning when I demo'd for teachers - but this afternoon it deleted student from photo and added a random stranger!! Not good! Please investigate?

Hi ​@Peta de!! Thans for reaching out!

This is a known limitation and our team is working on this limitation in the tool. Currently, if the object you're trying to remove is very prominent or is identified as a key subject rather than a distraction, it may be substituted instead of being removed.

One tip that may help is to include some of the surrounding background when brushing over the object. Rather than making a very precise selection, try using a slightly broader brush stroke to give the tool more context and improve the result.

If you're still not getting the desired result, you can try Remove Object in Adobe Firefly as an alternative in the meantime.

Hope this helps!
