Hi,
pardon me it that's a silly question but I'm new to K2. So far I think I already figured some key points around categories, items and extra fields. But I'm wondering why I can't reorder the extra fields in the admin panel? Order arrows are grey and the numbers can't be overwritten. It's acitve for items and categories but not on the extra fields page. What have I overlooked? Using Joomla 2.5.4 with K2 2.5.6

Thank you!
Susanne
