I have PROBLEM !

Hello.
I have a problem with Dolphin 7, and specifically with the modifications / removal of fields available for recording and later in the profile - it is about growth, age, etc.. Fields profile option is not loaded to me, that says loading, but nothing happens even after an hour.
Please help, any way / free module that will allow me to delete these fields.
Thanks in advance and greet.
