This is a really easy fix for sticking L1 & R1 buttons on your PS4 pad - which seems to be quite a common issue.
Carefully ease the button out by gently levering from the top and clean the button and hole with a cotton bud soaked in screen cleaner. This will remove any sticky dirt thats built up during play :)
To re-insert line up the two mounting points and firmly push the button back in until it clicks into place.
Then simply enjoy your fully working pad again!
