Cannot remove an action from a GPT

ChatGPT Bugs
1

I added an action to my GPT, later decided is not necessary and wanted to remove. But when I remove it and clean the name, description and url fields, I get an error saying:

Couldn’t save OpenAPI spec due to errors:
Could not find a valid URL in ‘servers’

How can I remove an action, all actions?

My fault, there is a “Remove Action” button in the bottom left corner of the modal (:
