FUNC Breakable with NULL Model Fix?

[Sovario]

Is there any way to go through your map, fixing this problem easily? I have many, many breakable things and I don't know what to do.

Yes...

Press uh.. i think it's L

Then delete all func_breakable entries w/o an error next to them (in Radiant 1.5)

Find the func_breakables with L that don't have a arrow to expand them on the left-hand side.
