How can I remove "User Defined Runtime Attributes" in Xcode and what are they?

In Xcode 5.0.2 I've created a new Master-Detail Application - and it worked well on iPhone and iPad simulators.

But then accidentally in User Defined Runtime Attribites in the right panel of Xcode I've clicked (three times) a plus and added "keyPath" entries (without really understanding what they are):

enter image description here

How can I remove them please? Clicking a minus doesn't change anything and running in simulator now fails with:

User Defined Runtime Attributes are just that: User defined keypaths that may not be available in the standard interface builder editor for a given class/control. When you click to add one, you instruct the NIB defroster to call setValue:forKey:, in this case with the keypath keyPath and the value NO (or rather, @NO). Naturally, as UITableView has no keypath or property named keyPath, the KVC mechanism will crash.

To remove one, it must be highlighted, then either the delete key or the "minus button" will work:

If the problem persists, file a bug report.
