"A Tempo" changes playback tempo to 120
For some reason, when I put "A Tempo" in a score, it reverts the tempo to 120 BPM, regardless of the tempo the piece was at. My composition has a tempo of 65 BPM, and the "A Tempo" I placed after a ritardando, which isn't supposed to affect playback, is still reverting it to 120. I had to do a tricky process that caused just one sixteenth note in the piece to have this effect, but this is one note more than it should.
Is there anything going on? I appreciate any help.
