Step count is always zero!

Hi, after reading all the related topics and having reinstalled Facer and Fit (to Facer 5.1.18_101299-(101299) and Fit 2.18.12-130), step count does not work, and is always showing zero steps. When I select a watch faces outside Facer, like the ones that comes with mi Ticwatch Pro, then it´s working fine.
It seems that this issue was fixed in Facer 5.1.5, but I´m afraid it´s happening again… Thanks in advance for any information about how to solve the problem.
