Yes, that is a frequent problem with Blackboard dashboards, and generally, it is a sync or cache issue. So the sequence of actions to fix the problem would be logging out and back in, clearing your browser cache or opening Blackboard in an incognito window, checking that you are using a supported browser, and if your ROTC courses are still not showing after a few hours, getting in touch with your ROTC admin or Blackboard support as course enrollment is usually a manual addition or there is a delay in the updates.
