Bug Report 3.19.1 - Step length - pips and beats.

The console allows me to program the step length in a chase cue list shorter than a beat (shows it in 'pips') but as soon as I exit the window, it goes back to beats. So for example I want to have the cues have length of 4 pips, while I type this value, I see the loop has the correct length, then I close the playback option window and instead of 4 pips it's now 4 beats.

Is it done on purpose or just a bug?
