Too many Data fields in Custom Ability

Hey,

Everytime I try to create a custom ability based on an existing one, all the data fields appear on it and it's just a mess to look through them all. Even if i copy an ability, still every data field appears.

Is there a way for me to clone an ability so only the data fields from that ability appear?

I see two things:

1.) You will always be basing a custom spell off an existing one. You can't jus create a new empty spell.

2.) There is a thread about this problem already: https://www.hiveworkshop.com/forums/world-editor-help-zone-98/object-editor-data-233977/
