Does anyone know how to deinterlace a clip on the timeline in 10.6.6, the check box in Information has been removed

Does anyone know how to deinterlace a clip on the timeline in FCPX 10.6.6, the check box in Information, which was there in the previous version, has been removed, and while some clips will deinterlace when added to a progressive project this is not always the case and I have large library of interlaced clips which I would like to be able to make use of.
