Branch selector Not Working

[toneware]

I created a private Angular project in StackBlitz (SB) (https://stackblitz.com/edit/macs-dashboard) using the following git flow:
master -> dev -> feature/ip-auth

I did the dev in SB using the feature/ip-auth branch.
I pushed to the branch from SB. Github updated properly.
I created a PR in Github to merge feature/ip-auth -> dev.
I did a squash & merge of feature/ip-auth -> dev.
I let Github delete the feature/ip-auth branch.
So far, so good.

Now, however, I cannot get SB to change branches -- it consistently stays on the feature/ip-auth branch. This was the current branch when I did the merge.

If I click on the dropdown, it does show the proper branches available (dev & master), and it allows me to select either option. It will not, however, toggle to the selected branch.

It gets even weirder, because it actually loads a working branch, and my app runs as designed. I can't tell which branch it has loaded, as dev and feature/ip-auth have the same code (the merge was successful). I tried selecting master, and it says that it's loading/compiling the branch, but the app that gets loaded has the dev|feature/ip-auth changes, and the branch dropdown still says feature/ip-auth.

I tried the following, to no avail:

• Close & re-open Chrome, nav to SB,
• Close & re-open Chrome, nav to Github , click on the "edit w/ SB" link.
• Close Chrome, open incognito (Chrome) window.

I don't have Firefox loaded on this box, and IE won't even load SB, so I didn't try either of those.

Edit: When I refresh the project, I see this pop up:

Once again, the selector still shows feature/ip-auth

I found a workaround:

• Delete the StackBlitz project.
• Create a new SB project (of the same type, blah-blah-bah)
• Import the GitHub repo (in my case, I imported a new branch that I had created off of dev).

This is far from ideal, but I am able to get back to work.

Edit: This does not rename the SB project, FWIW.
