THRESHOLD SWITCH NOT MOVING PAST 25%

So I have been playing for a while and in the start it seems as if my Threshold switches worked, but as of late they all just stay on 25% capacity, even if my Max size vault is full. I tried moving them, changing the placement (top detect and bottom detect) , but nothing helps. They just never seem to reach the top Value of lets say 75% and thus machines never turn off and this results in items spills and well Lag.

I am currently using Create Version create-1.20.1-0.5.1.f

I am not sure if there is a bug present or if something has changed. Any help would be greatly appreciated.
