Annoying Issue with PTEF

Hello everyone, Im having the failed to pull error that is very common.

I don’t know how to fix this issue, Not sure if its the same issue that everyone else has had.

I have a brand new AMS and i keep having this issue only when the first slot when it tries to load filament in.

The way i get it to work is by just moving the ptef tube while its pushing the filament in between the grey adapter that connects the ptef tubes.

But it only happens when the fist slot pushes filament. Works fine with the other slots.

Sounds like the PTFE indicated is not fully pushed in or is not cut perfectly straight.

Buy why does it only happen with the first slot of the ams?

While loading different types of filaments, or just one type?
