Database Alter & Delete greyed out

I have moved a few NAV databases to Azure SQL. When I open any of these databases I cannot select the File > Database > Alter or File > Database > Delete options, these options are greyed out. The only two reasons I can come up with is that is must be the user rights on my Azure SQL user or maybe the license file, but the user is both db_owner and the equivelant to sys_admin on Azure SQL, and I tried using our developer license.

The problem is the same in both single- and multitenant databases.

I hope someone here has a solution or any suggestion I can try out.

Thanks!

Best regards
