Drop 120fps into 24fps timeline get Media Offline

In 17.2.2 if I drop a 120fps clip into a 24fps timeline I can see it at 120fps. But if it is already in the timeline and I change the clip attribute to 24fps to get slow motion, it goes offline. But if I change the clip attribute while it is in the media pool before I drop it into the timeline, or even reinsert the clip into the timeline after I have changed its fps attribute in the Edit page, it works fine as a slow motion clip, though the first iteration of this clip stays Media Offline. I’ve checked to see that Realtime and Scaling are not set to Optical Flow, and that Render Cache is off. Is this a bug or am I missing a step or two? It did not do this in earlier versions.

My guess is that this happens because the internal database keeps track of clip position with timecode. If you change speed while it's in the timeline, the timecode changes. So I'm "guessing" this is what happens. Not sure if this is my design or a problem.

I suggest do not touch the attribute for slowing down your clip, but use right click on it and use the 'change speed' option instead.
