I am trying to set up refspecs for a project according to this guide, and they specify two glob refspecs to be used:

+refs/heads/*:refs/remotes/origin/* +refs/merge-requests/*/head:refs/remotes/origin/merge-requests/*

However, I just get a "Specification is invalid" after entering these and cannot proceed.

Each refspec individually works, just adding them both at the same time does not. Adding two refspecs w/o globs also works.
