This is something that I've noticed in 5.0.2....
When you change the length of a MIDI loop from say 1 bar to 1 bar and 4 beats (assuming you're in 4/4 timing), the loop correctly changes to 2 bars, but the text fields say 2 bars and 4 beats. As in whatever got automatically modified (1 bar + 4 beats = 2 bars.... no shit hey) doesn't get updated on the screen. It still works fine though.
