What does "Account limit reached… Remove one to add another" mean?
Short answer: You've reached the number of accounts allowed for that provider, so it's greyed out. Remove one you don't use in Remotes & Accounts, then add the new one.
Storage Studio limits how many accounts of the same kind you can add, and you've reached that limit for this provider — so its button is greyed out in the Add Account sheet.
To add a different account of that kind, remove one you no longer use in Remotes & Accounts, then add the new one.
