Looks like the PGOs are not updating. If you there has been any activity on the servers, all those files should be updated. TicketData keeps the session IDs assigned to each user and CalData keeps track of the usage of the licenses (you can see in the Events log that a license has been assigned or stopped for any named user logging).
I would suggest you to contact Qlik Support in this case, but you can also try to stop services, copy those files in a different folder as a backup, and start services again. The files will be regenerated, and license allocations will be gone but all the files will be fresh, in case any of those is corrupted, this would solve it.
