Welcome to the forum. I am not familiar with your coach specifics but my first thought is did you climb up a ladder and visually check to see if there is something on the bedroom slide roof preventing the slide from closing at the roof seal? Also it would be worth checking and advising which hydraulic slide system you have and then see if you can obtain a manual on line (if you don't already have one) or contact the manufacturer directly to determine if the slide system can be adjusted. I hope you just find a simple jam is causing your issue.
