Iron Golems do not spawn in forceloaded chunks

i was messing around with the new force load command and i thought let's build a iron farm and i've let it run all night on the server with people on and no iron golems did spawn while there was no one around even though forceload is on. when i'm nearby iron golems did spawn.
the iron farm is in the middle of the chunk and i've force loaded some surrounding chunks as well.

i know it works for spawnchunks but not for forceloaded ones.
