GoogleFit and MiFit - different amount of steps

Hello guys,

I got a strange problem with MiFit and GoogleFit Sync. I do have a Mi Band 3. I am using the MiFit App and let it sync with my Google Fit account. The number of steps are not the same.

This is what MiFit tells me:

GoogleFit shows me this number of steps:

Does anybody have a solution for this problem?

Additionally I got the proof now. GoogleFit still counts steps on its own. I cut the link between the MiFit app and GoogleFit. I also stopped the step tracking for GoogleFit -BUT GoogleFit still shows steps. For the moment there are only a few less than my smartband tells me because I had my phone with me most of the time.... So it doesn't make a difference if you don't another so that counts steps or not. Additionally GoogleFit doesn't care about its own settings
