Problem with radios & lights

This is my house.

Upper circle: Radio A
Center circle: two lights/candles
Lower circle: Radio B

One problem is when the sims sit at the dining table next to radio B they mostly use Radio A.

Also the highlighted lights are on depending on where the sims are sitting. When they are at the dining table, the right light of the two is on. When they sit on the couch next to radio A, the left light of the two is on. The other lights on the walls are on properly when sims are only in that room.

Yes, despite the grey lines not being connected properly, those are all seperate rooms. Not one wall piece missing. There are half walls, columns and doors. Totally normal.

I cant make sense of it. This is pretty unique in my game. Im currently considering removing radio A because it looks buggy for sims to use a radio thats technically in the next room.
