Work Card for Machine not Updating

Recently I have had issues where the work space card will not update the last time it was updated. I've seen it where I have currently been working in it and it will say that I haven't updated it in 5 or 6 hours. I have also seen where it will say that it hasn't been updated in days right after I have worked in it. Has anyone else have this issue before? It hasn't quite affected anything in the work space but it has been something I have noticed. Also, I have been able to refresh the page and it will display various times as to when the machine was updated without even opening the machine again.
