All icons showing with N/A and Classified gallery broken

I have the pro version of the plugin but this happens even with the free version. Every icon possible is showing on the specification tab. The ones that are for DVLA are all with N/A as I don’t use that, they are also duplicated and I can’t find the entries in the DB to delete them. When I save the extra fields for comfort etc, they don’t save and revert back, so i’ve had to put a space stroke in those. The Classifieds gallery displays one image above the other. My client purchased the pro version plus Corify but then became ill so the support has run out via Them Forest. Are there simple fixes for these issues?

I have tried deactivating all plugins except the essential ones, zero change. I installed Jetpack as I saw a post that was needed, but now that is all in separate modules and don’t know which plugin module is required (if that is the case). Pulling my hair out here as the client just wants a basic vehicle sales section for his garage, nothing fancy at all.
