There are many ways to remove the plastic tabs.
You can use something like tin snips to cut them or a pair of pliers an snap them off,the wet saw can cut them off or you can just tap them with the rubber mallet to break them off.
No exact science just whatever works best for you. but most of the time the tabs are removed allready because most of the time the tiles at the perimeter are cut to size and the tabs would be removed then.
Good luck! let me know what worked best for you.
