Is it possible to update/change a claim pages Twitter Claim Page URL?

I’ve had to change my Twitter name. In the edit claim options I have attempted to change the Twitter address the claim page is attached to, however, the area remains grey and unchangeable. Is there a way around this, or is the Twitter Claim Page URL permanent? Thank you.

Could you please give us more info? What is the link to your claim page? What wallet do you use with studio?
