Hi I can't deleted custom form fields and they show up as duplicate fields. The only way I have been able to delete / hide these duplicate fields is to select hide. When I try and delete a custom field I get an error message which just says "Error on delete!". Also, I have tried to add : at the end of the custom field, for example I have a label with a Slug of name and the label of Name. I tried to change the label from Name to Name: it saves ok but when I refresh the page it goes back to Name. Am I doing something wrong or is there a problem?
