Subpanels empty and useless in Suite7-theme on 7.8.13-LTS

I after first upgrading to 7.8.12 all the subpanels stopped working with the Suite7-theme. I just upgarded to 7.8.13, and there is the same problem. There is no content, and also i can’t add eg. any contacts because the controls are missing…

Any ideas if this will be fixed, or do i need to do a downgrade back to a previously working LTS-version?
