Filament Won't Latch To Extruder Gear

Hello,

I've recently acquired the MMU3 for my MK4S (both latest firmware) and it seems that when the filament gets pushed from MMU3 to MK4S it stops just before it gets pulled by the extruder gear. How can I solve this? 

Before the upgrade my MK4S worked perfectly fine. I didn't tweak the MK4S after installing the MMU3. I flashed the latest firmware onto the MMU3 from my laptop. Printing only works if I take off the tube and push the filament to the gear but this is clearly not the solution.
