I apparently have not enough channels for any of my busses anymore since i moved my controller. I feel like im being an idiot but many thanks for the help.

well ... a fluix cable only handles 8 channels even if connected to a controller

and a single dense cable attached only provides 32 channels in total ... so if you need something like 128 channels, you have to attach 4 dense cables and branch out from your controller, you seem to have misunderstood the function of the controller ... it only provides 32 channels per side and acts as a relay between cable segments that can handly only so much channels themself

also be aware, blocks can only handle 8 channels, so any interconnected blocks can only share 8 channel to its neighbours
