(macOS 10.13.5, Finale 25.5.0.259) I am trying to create some exercises where students have to identify problems in key signatures, For example, containing accidentals that are on the wrong position, or in the wrong order, etc.  I have tried to follow the instructions in the manual for not-traditonal key signature and changing the order of accidentals, but my results make absolutely no sense.  Most importantly, I seem to be unable to create flats only sharps.  Is there anyone, who might be able to provide me with a stepwise approach to create the following three problems:

1.) An A-flat by itself (as a wrongly placed flat in the key signature of F major)

2.) Four sharps in the order of C#, D#, G# and F# (Key signature of E major but out of order)

3.) Three flats: Bb, Gb, and Eb (Key signature of Eb major but out of order and with wrong pitch)
