Cant update Divi Theme

Hi there this is a new multi site and I am unable to update to my latest theme. I am using Divi and they dont offer an automatic update. I did this before with another multi site network and I am not sure what is going wrong this time around. I need to delete my old version of Divi but it wont seem to delete. When I try to install the new version it says I have to delete the old one first and when I try to just activate the old one it says that version has already been deleted. Thank you for any help.
