Take a look at berlin-hack-and-tell/bhnt.c-base.org#320 and you'll see @dependabot tying to merge the update from 0.0.27 to 0.2.31.

It is confused by the version scheme change.

Since you cannot remove "old" version, I suggest changing the version scheme again. Since you want to match URLchecker, then you should use major.minor versions only. e.g. 0.0.27 becomes 0.27.

That will fix the issue since 0.27 > 0.2.31 > 0.0.27.
