Grey box on Composition Background Cant get rid of
Been working on a project for two days and everything's fine. Today I did a little square grey box for a track matte. Didn't like it so I deleted the layer. But box stayed on screen. I disabled every layer trying to figure out where it was but it is not on any layer. Somehow it seems it ended up on composition background and is visible in every layer. Anyone know why this happened or more importantly how to get rid of it without starting over?
Thanks.
