Front timing cover removal

Currently in the process of removing the timing cover, I have the majority of everything out, and have the timing cover ready to come out, but when prying it open the top side would have a gap but only flex and not peel back, was wondering if there is anything I am missing, I tripled checked all bolts and made sure they were removed, alternator removed all pulleys removed. I do only have two bolts removed from the ac compressor that bolts into the timing cover removed ( I dont know if I have to remove the whole a/c compressor) the three bolts in the oil pan was removed as well. was wondering if I am missing aything
