Problem with NSTableView constraints

Hi, the problem is not dangerous to life, I don't want see the yellow button on top of the editor. 'Autoresizing Mask' is set to about 50 items, that works, except tableView, 10 warnings. The tableView has 10 columns of 20 pixels width, min 10 and max 100000. The ' Add new constraints' options are all grayed, so what ? In an other project a warning was set for arrayController, I don't like Auto Layout, the blue help lines are enough. My question is : How do i can suppress this warnings ?

Kindly, Uwe
