Ultimate Keeps Resetting to Default After Patch

See title. This was not an issue I was having whatsoever before the N7 Day patch, but after patch my ultimate keeps sneakily resetting to the default one instead of my specialization ultimate. It does seem to help if I swap between the two a few times when I notice it's reset, but it does eventually happen again. Restarting the game client can also temporarily resolve it, but has the same eventual recurrence.
