Broken alarms - am I missing something simple

[legoman]

We're in the early stages of deploying IMC, so only a small portion of our switches are added at the moment. We did a big upgrade this morning, so would have expected to see a lot of alarms... which we did.

However, now everything's back up and happy but IMC is reporting unrecovered alarms that don't exist and warnings that I can't find at all.

I'm starting to fear this software is a mess. I'm hoping I've just missed something simple/stupid. Do let me know if this seems familiar - 

Here's a short video showing the issue:  https://youtu.be/h4dlJpTi1R8

As I predicted, after a reboot all the switches with unviewable warnings are now all ok. :(
