Those showing undefined sounds like a bug from the Forge’s side, though I haven’t seen that before, so not sure what would cause it. I also don’t know what the error is (you should have seen a notification with more detail for why it failed to update those). Either way, they look like premium content, so I would recommend using this guide to install/update them : Installing/updating Licensed Premium modules (specifically the part about the optimizing of the data since we can’t touch it ourselves).
I quit my browser and walked away. Got something to eat. I returned several minutes later and tried again.
Foundry will migrate some of the compendiums data after an upgrade and that can take a while for some people, during which time, the Foundry server itself is completely frozen. Not much to do other than walk away and get something to eat, so you actually did the recommended solution there! 
Let us know how it went during actual play, I hope it was smooth from there on out!
