dt not importing version 0 upon re-import

Starting with darktable-4.3.0+704, I believe, after downloading a raw and the different sidecars from a Play Raw, duplicating version 0, and applying the sidecars to the duplicates, if I then go to another folder and then come back to the first folder and re-import it, version 0 is not included in the versions shown in lighttable. I made no changes to the settings when I updated. I am now using darktable-4.3.0+975. and the problem persists.
