Remove SQL modifications after uninstalling and unpublishing NAVapp

Hi,

I Created an Extension in BC, and it works fine. After testing I like to remove it entirely.

After executing the following powershell commands:

Uninstall-NAVApp -Name 'The Name' -ServerInstance BC130 -DoNotSaveData
Unpublish-NAVApp -Name "The Name" -ServerInstance BC130

All seems to be removed in the webclient, but when I look at the tables in my sql server mgt studio all
extension modifications still exist.

Is there a powershell command that solves this?
I tried
Sync-NAVTenant -ServerInstance BC130 -Force -Mode Force

But that is not working.

Help would be appreciated!
