Target branch dropdown for branch comparison not working

Are any other organizations/individuals having the problem with GitLab.com where, when trying to compare branches (see specific steps below), the Target branch dropdown does not show/find all of your branches?

  1. Navigate to a repo.
  2. From the lefthand navigation panel, choose Repository → Branches
  3. Pick a branch and click the “Compare” button.
  4. Try to select various branches as the “Target”. Note that only a few of all of your branches are actually available to be selected.

For example, we have a ton of branches named “feature/{something}”… but our Target dropdown does not include any of them just scrolling through it. Further, trying to search for them doesn’t show them…nothing shows up once you get “fea” typed into the box. (Prior to that, a tag that starts with “fe” shows up, but no branches that start with “fe”.)

This issue first appeared yesterday. Multiple (I think all) of our developers are experiencing it. Clearing browser caches, rebooting, etc. does not fix it. (We are a Mac shop–Mojave 10.14.6–and use Chrome–Version 89.0.4389.72 (Official Build) (x86_64).)

Of interest is that the Target dropdown box for creating a merge request directly does still work right.

  1. Navigate to a repo.
  2. From the lefthand navigation panel, choose Merge Requests
  3. Click the “New Merge Request” button.
  4. Try to select various branches as the “Target branch”. Note that all branches are available to be selected.
