How to remove bypass doors?

Hi - Am puzzled how to remove these sliding by pass doors - have tried releasing the bottom rail plastic guide and then tilting the door outwards from the bottom to supposedly release the top roller - but the top which has the 23-027 rollers won't seem to budge - the top roller on the outer door in particular seems to run in a channel that partly encases the roller at both its lower and upper edges - any guidance appreciated - Thanks!!

Sometimes this type of track has a cut out where the rollers must be before they can be tilted out. Look to see if yours has one.

Managed to get them out,while the door was being tilted outwards at the bottom as is usually done to remove them, also had to pry the top wheels a bit outwards with a screw driver behind them .... Thanks
