Invisible Caesura (not grayed out, but gone completely)

I had set a caesura on every instrument at the end of measure 20, but intending to revert the change went about deleting all of them. I can't remember if it was a bulk selection or individually, but now all the caesura's are gone visually yet playback still pauses for the originally set time every time it reaches the end of measure 20, and I have no clue as to go about rectifying it outside of excising the entire measure and rewriting it by hand.
