Alto sax lags when moving from concert B to C in the upper octave

I went to write a 4/4 bar that had the notes in order played as (in concert) F, G, B, C and for some reason the playback lags going from B to C, and seems to treat it like a dotted quarter + swing eighth. Very frustrating. I tried moving it to the lower octave and it worked perfectly fine, I tried moving it to a different place in the bar (to the offbeat, or to a different beat other than 1) and the issue replicated. I also tried changing the duration of the B and C to eighth notes and that just cut the C out of playback altogether. I know when I print it playback won't matter but this is a very strange issue.
