Polyend Tracker - tempo fx odd times

Anyone know why I can’t set the odd times on step Tempo Fx?
I’m preparing a live with some of my songs (I uploaded the samples on sp404 connect via midi with polyend) and I have several tracks that I’d like to insert in different patterns but many tracks are 69bpm or 75bpm, do you know how I can do it?

It’s been flagged in the GitHub I think…
