Hi Scott, It is a bug in nrfjprog. Seems like --sectorerase can't erase UICR. And it result in the warning you saw. But if you do a --eraseuicr prior, you should be fine.

I don't know if that is the right way but I use nrfjprog -f NRF52 --recover in my scripts, it erases everything including UICR so I'm good to go with programming the entire chip from scratch. Also note that there is --sectoranduicrerase switch for --program command in the latest nrfjprog version, that's probably what you want.
