Deinterlacing problems

Now that the deinterlacing option has been removed from the clip attributes, I'm getting horribly interlaced images on my progressive timeline.
I must be doing something wrong. I don't see other people complaining here. But I'm getting kinda desperate. Tried setting the new high quality neural engine deinterlace on and rendering with optical flow. Nope.
Am I missing a switch somewhere? I read the New Features manual. The 16 manual is wrong. It used to be so simple. Just turn on deinterlace and it worked.
It seems wrong to have to deinterlace the clips outside of Resolve now, but I think I'll have to do that.
Now what?
