I am also having a problem with the clear filament. Initially, it was working but unfortunately, the filament seemed to have been intertwined in the role and was stuck in extracting.
I had to cut the filament and re-do the insert new filament. Afterwards, the filament was going in without a problem but seemed to be stuck trying to feed it through the nozzle. Print jobs was going but no filament coming out. Re-did the insert new filament about 2 times but still didn't want to take.
Finally, tried the black filament and no problem at all. Print is working and everything is great. Later I might try the clear again but for now, i am avoiding it.
