edge flance not flattening

Is there a bug in Solidworks 2016SP5 that sheet metal edge flance parts are not flattend by the flatten command? because of some weird reason i can't flatten it while the other bends do flatten (Sketched bends)

Edit: All bends i add now won't flatten like it suposed to. Bounding box does give me the right size tho.
Added a screenshot in which u can see the problem
