You have short term trims in the datalog so closed loop appears to be working.

Look at the fuel status. 2 is closed loop.

It runs in closed loop for the first minute, then after the restart it again goes into closed loop again.

I'd look at the injector dead times first and then why there is a -20% fuel trim.
