Jobs assign resident not recognizing cairn upgrade. with workaround

Still not sure if its something i missed or if this is a bug.

Major card- Abeyance forest realm
Minor card- Naughty and Nice list

had pre-existing t1 estate cairn built in abeyance realm
purchased T4 Estate Cairn blueprints at watch
did not purchase t2 or t3 progression tab cairn blueprints
built T4 estate cairn ~10m from existing cairn.
interacted with t4 and chose the "create respite" option and then "Move Estate Center" option
could assign new residents to built stations but only up to 6. That is with both a T1 and T4 cairn present.

travel to respite warp option would return me to the T4 cairn location.

moved T1 cairn roughly 73 meters away from the T4. still capped at 6 slots

demolished T1 cairn via build mode "X" remove function. still capped at 6

workaround / self-fix
built another T4 cairn roughly 19m away from the original T4 cairn. assign slots went up to 15

game stats pic is after fix was achieved. sorry, didnt think to grab it while issue was active.
