beat detection under 60 bpm

hello, the auto beat detection does not work under a beat of 60 bpm.
so if we give onyx a beat above or at 60 bpm it mostly work and detect the right bpm. but under a beat rate of 60 bpm there are everytime different bpm detected.
can someone explain this behaivior?

I had also requested slower audio reaction features such as beat detection. The answer given was to use the beat divider. (I hope that it’s a temporary measure, no pun intended.)
