Key signature not allowing a specific key
I'm recording a song in Eb major, and I'd like to be able to use loops / the score editor. When I try to select Eb major in the key signature dropdown, Logic selects Ab minor. I've tested this in multiple projects, and have restarted Logic, and it still occurs. Other key signatures can be selected without a problem. Any idea what's going on here? Or, has anybody else experienced this problem?
Logic Pro X, OS X Yosemite (10.10.5)
