GNSS S-JTSK (EPSG 5514) projection problem

This is the positioning setting using directly connected to GPS via Bluetooth (location totally off)



This is the position setting when using mock location via native app from South (LBS Manage). This works, but the position is consistently about 1m off in both x and y. This problem is exclusive to Qfield, in other mapping apps the location appears to be correct.
