Key Signature variation

[adlibitum]

good morning. I have a problem that I cannot solve and it has happened to me several times. I imported a score from Photoscore, and I don't know why Sibelius, at one point inserted a key signature variation (3 natural instead of 3 flats). When I want to erase it, the notes (which would be written right for the key of Eb) are altered by Sibelius. I would like to remove the variation, but leave the written notes as they are. How can I do?. Thanks
I attach 2 images.

At a guess, I'd say you probably need to do more corrective work in Photoscore before importing. That's often the cause of such issues. Try going back to the Photoscore file and re-working it.

OK, you are going to hate me for this, but it needs to be said:

Before going anywhere near the "Send to sibelius" button YOU need to make sure that PS has not inserted any stupid key changes. It WILL do this. You can't abrogate responsibility for checking BEFORE you send to sib.
