Yes, problem has been fixed on your server. It is really bug in 10.4.4 version - if you have 2 database servers: Mysql and MSSQL and if you set MySQL databases=0 in subscriptions settings, "Database" icon will be hidden in Control Panel in spite of MSSQL databases are not 0. We will fix it in nearest MU#13 as soon as possible. Sorry for inconvenience and thank you for cooperation.
