delete fields does not work?

I do not want to change your plans. I will mark as optional and hide the wrong fields as you release a new version whenever it is planned. Thanks again!

Hello all!
I’m working with an spanish traslation and I got all the errors when trying to delete either a field or a group.
To solve this, even though is not a real solution, I switched my wordpress language to english, then erease all the things I want to erase, then get back to the spanish language on the general settings.
It worked, the erased fields and groups never came back.
Hope this work for you guys!
Thanks for this amanzing plugin! ??
