Hi,
i was testing different things in Insights while creating our Schema.
I tried to add addtional reference types for better filters. I entered "Test" into the field and pressed enter, hoping it would automatically add a new type.
This did work.

I then tried to remove it, which didn't work.
When checking the Global Configuration, "Test" did not show up.

For testing, i added another "Test" in the Global Configration, which then results in a duplicate entry.

I can delete the second Test just fine, by editing the Global Configuration, however i see no way to remove the first Test.
How can i clean this up ?
Regards,
