Yup sounds like it's out of sync, whatever you do don’t force the thing mine got stuck down just before a sudden shower and I worked it shut.. Well $1600 later I could close the top and the cover went back down like normal.
(I got off cheap for the amount of damage
) If you are going to try to fix it yourself check out

Best of Luck!
