2.37.2 can't "git pull" but 2.18.0 can

I'm testing an upgrade to git 2.37.2 from the current version we're using of 2.18.0. When I try to pull in my development tree, 2.37.2 gives me an error but 2.18.0 things all is fine:

$ /tools/linux-x86_64/git/2.37.2/bin/git pull Your configuration specifies to merge with the ref 'refs/heads/feature/switch-to-qt5' from the remote, but no such ref was fetched.

$ /tools/linux-x86_64/git/2.18.0/bin/git pull
From http://githost:7990/scm/dp/sw
 * branch                  feature/switch-to-qt5 -> FETCH_HEAD
Already up to date.

Anyone have any ideas about this? All I could find on google was a suggestion that the "no such ref" message indicates the remote branch was deleted, but that's not the case here.
