Upgrade Database

I create few entyties starting from an existing database. On first run of application cuba require to update database, I opened DB Manager, and I seen that is has created only few script with create index on tables imported, then I run this script.
Now all times that I run the application, it recreate same scripts, with same name with counter 01 post file name. It seem that not recognize the previous upgrade database. I am using SQLServer

any idea ?

Which version of CUBA Studio do you use?
Is the database connected as main (or additional) datastore?
Are you sure the scripts were successfully applied? Do you see them with the applied status?
If yes, could you share the scripts(a couple of them) here?
