Incorrect time in onstep

Hi,
I’m getting to the point where I’m giving up with this mount & going to return it.
Basic setting for time is constantly being changed. I’m in GMT so I set the date & time in the HC to 15.00 with DST as no (as per the quick setup guide).
As soon as I connect the mount to any software like NINA, voyager or sharpcap the time in onstep changes to 14.00
Can anyone tell me how to fix this please

Hi

I guess its the same like i posted here?

If I overwrite the mounts data with the GPSD data (usb dongle), everything looks cool
