'88 Vanagon 4spd
Recently everytime I press in the clutch pedal and release, the pedal only returns a few inches and sticks in place.  Clutch is still engaging as normal and no problems with driveability or shifting...yet.  A slight tap under the pedal with my toe and it springs back to its normal position.
I have checked for leaks at Clutch master cylinder and slave but do not see any signs or drips.  Been watching the fluid level and have seen no signs of fluid loss.

Could this be the sign of air in the line or a bad cylinder.
Clutch pedal has always had a slight squeak when pushing in the pedal.

Any thoughts are appreciated.
