delete to clean text outside of a dialog

Hi, how can I prevent this type of text from being detected and deleted?

Impressive that panel cleaner managed to detect that properly! Usually it doesn't. I don't know your workflow, but I'd recommend exporting in a layered format or masks only. Don't use the cleaned images directly.
In your image editing software (photoshop, gimp etc.) You can layer the mask on the original to have the cleaning effect. For stuff you didn't want cleaned, you delete that part of the mask. For stuff it missed, you can now clean it manually.

That's how I'd do it and then this issue solves itself, because unfortunately there isn't a way to detect this case automatically, sorry.

I hope that works for you.
