Can Trim Reg in ADP1048 be programmed when loading register settings?

I'm using the adp1048 for a interleaved PFC application. In the prototype I configured the register and board settings that everything was running smooth. I saved these Settings using the button in the GUI. Today I had a got a second hardware and I loaded the previous saved Settings to the ADP1048. I doubled checked the loaded settings and there was a mismatch between the TRIM values. I used the spy window to check whether the TRIM Registers are written or not and there I could see that no TRIM-values are written when loading the register settings. Is this the expected behaviour? How can I change the trim values without doing it manually?

Would be very thankful for help.
