Bug in rendering track which is scaled, offset and cropped

[sheetsofsound]

Davinci studio 18.6 incorrectly rendering tracks.
_[edit2] FOUND A WORKAROUND. Thanks @maximilian yuen.
copy the offending timeline
create a new project in same res as the offending one. Has to be a new project. Creating a new timeline in existing project doesn't affect this issue.
paste the timeline.
Save / Restart Resolve (this is the key)
Timeline now renders ok.

[edit] it seems to be a positioning/scaling bug. I changed my project settings to convert to horizontal format and you can see by the additional photo i've attached here that when it does the render, it's positioning the clip way off to the right. If you look close, it's also incorrectly scaling the crop. The crop should be a closeup of my right hand but if you look at the last photo, you can see that in addition to moving the image outside of the vertical frame, it's also cropped it incorrectly so that my hand is no longer framed but instead it's framing the guitar neck._

First image shows what it looks like in editor with annotations. V2 is completely missing from the render. V3 shows up in the render but the crop on the right side is incorrect.

2nd photo shows final render.

I have tried render in place, deleting cache as well as creating compound clip. No change in behavior. One interesting note is that if I render V2 in place, it immediately disappears in the edit view.

interestingly enough, if I set playback to disable all proxies, the v2 clip just disappears totally. I went through and deleted all proxies, all cached data too. The only way the clip reappears in the editor is if I re-enable caching and regen the proxy for the particular clip.
