mmu2s wont load to nozzle but loads filament

so i just got the mmu2s for my mk3s+ and this thing is more issues than my ender 3, i get the mmu to load filament without issue, the mmu will grab and load and the finda does detect filament however when i click load to nozzle the mmu only feeds like 5 mm and then the extruder kicks into high gear however no filament made it to the bondtech gears and finda is fine. i tried to add as much info as possible and i also checked the prusa knowledgebase and did the calibration and everything. im at a loss as to what to do.

The MMU only "kicks into high gear" when the finda sensor detects the filament. If the filament doesn't get in to the PTFE tube between the MMU and the extruder.

Unscrew the PTFE fitting on the MMU selector and try loading to nozzle again. The filament probably gets stuck somewhere in the selector or the PTFE fitting.

Also have a look at this video. It shows in detail how the MMU works and what steps it takes to load and unload filament.
