Deactivated Module Continues Appears in Menu Bar (Desktop & Web)

Hi everyone, after I deactivate the module, they still appears in the menu bar on both desktop and web versions.
But whem I try to access the module I get an erro.
Any advice or suggestions would be greatly appreciated.

Module deactivation is beta because it is very difficult to actually undo what module activation does.
It will probably require manual operation to clean the leftovers.

Could you explain what manual operations should I proceed.
I delete it from the ir.module table, but didn’t solve the problem.

You must delete records that were not deleted (normally trytond-admin raises a warning for those records).
You may also need to remove SQL constraint or NOT NULL that were added by the module.
