Adobe portfolio standard domain name change more than 5 times and now I can't change it?

I have a few various sites on adobe portfolio and after getting married I changed my name so I changed my adobe generated domain name. However, on one of my websites I likely already had changed the domain name to suit what i showing in the portfolio and changing things around since I'm not purchasing a domain anyways...now it's stuck on something and i can't change it bc i'm past the 5 domain name changes. 

I've spent so long eiditing this site and having to delete it and remake it just to change the domain come one there has to be a better way. I'm happy with the subdomain i just don't understand the 5 domain change limit. It makes zero sense.
