Unable to view hardware for managed inventory

I've recently taken over administering our Symantec CMS 7.6 application and noticed we are no longer collecting hardware information such as memory, etc. I've confirmed that the policy is enabled for the inventory plugin and that it is installed on the workstations I'm testing on. This feature was working previously and it is unknown what changed. Software inventory is working just fine.

The only change I've made so far was to uncheck the box stating I only want to collect changes (deltas) which had no effect.
