Can I claim ENS for multiple unused names on my wallet?

I've registered for 3 names years ago, but only used one. That one has registrant and controller set to my wallet address, with the resolver 0x4976fb03C32e5B8cfe2b6cCB31c09Ba78EBaBa41.

However, I've got two more names on the same address, yet without registrant and controller set. I don't remember what I did as it was years ago, but I can see those addresses with my working address in My Account on ENS Domains website when I have my wallet connected. However if I click them it looks like this:

What exactly is going on? I have the addresses listed, though I can't set anything, and can't update to the new resolver either. (everything grayed out) If I've just bought the addresses but haven't set the registrant, why does it also say "no address found" for controller too? If that's because that I'm using old resolver, why is migrate/set buttons grayed out?

I've received some ENS on my address, but I was just wondering is there anything I could do with these addresses that I've registered almost 4 years ago to get some ENS?
