Pcp Update to LMS 8.1.2

I am confused about how LMS updates happen with pcp. I am on pcp 6.1 (I will be updating to 7.0) and I have previously used the lms-update script to select the stable branch of LMS with nightly updates:

Now that 8.1.1 has been released, I expected the "Nightly Update" button to update me to 8.1.2 but I get "no updates available", I also get no update notifications. My LMS version is:

I had thought setting the release branch to "stable" should have moved me to the 8.1.2 release. Am I missing something?
