Tax groups - duplicate entries

In my tax groups, there are duplicate entries for most of them.


It’s not really serious, but caused me some trouble when trying to create tax rules. I cannot delete any of the, TRY says all of them are part of the basic configuration.

In spite of that - is there a chance to get rid of the surplus ones?

Cheers,

Are you using account_de_skr03 template?
Did you create multiple times a chart of account?

Thank you. You led me to the solution - I had two account tables at a time - SKR03 and SKR04, using only SKR04. So deactivating the SKR03 module (module page -> propeller menu) erased the surplus tax groups.
