I forgot to say that it depends where it is sticking. If it is the tab that the slot slides in the the above is true. If it is the sliding surface than a few light strokes of the file on each side of the block should ease it. a little at a time!
File flat on the table and run the side of the block along the file – not the other way round.
Also run a small amount of solder into the bend after you have bent them
