Control rig breaking characters. 4.26 premade and 5.1 rig pack

How do I fix this. I have 3 different characters that get deformed with missing controls in some way when applying a control rig. I have tried 2 different pre made rigs(the 4.26 and the new pack that just came out) and even tried the few tricks I learned (these tricks worked in 5.0 but do not work in 5 anymore or 5.1) I also even tried making my own custom rig and still becomes deformed with controls disappearing. I had 2 characters in 5.0 working perfect on the old 4.26 c.r. but since the updates they can’t seem to be fixed with the old tricks. please help day 5 of trying to fix this have been all over google and youtube. I do not know what else to try as I am still new and learning. The 4.26 rig I can get rid of the deformity, but now ALL finger and rotation controls disappear. The new 5.1 control rig pack still has full deformity and missing controls. Thank you for any help.
