Oscars are very intelligent fish so they will react to changes more than some other fish. I would suggest giving it just a couple of days and if they do not respond back to "Normal", you'd be wise to put back some kind of block to the back of the tank. That said, is the tank up against a wall of something where the scenery doesn't change? If not, it may be the intermittent movements they see that are upsetting them?
Just a suggestion, if you do need to put paper back up, a nice darker blue paper will show off the fish better than black will.
