I had three popups and it would happen when I didn't get it all the way up. This can occur just be accident or due to failure of the lifting arm(s) or the lifting cable systems.
Look at some youtubes on lifting system repair if lowering and raising the doesn't fix the height problem. The cable can jump off the pulley, a wire can fail or other parts in the lifting system.
Ps post your year as well as model and keep us posted on what happens.
