Doubt about Third Party Application

any idea why the “Global Software Inventory” shows that there are applications not up to date but‎ then, there is not sign of them in "Patch Management > Third Party Applications " ? In my case the app is called “Caldavsynchronizer”, most of the EPs have the latest version 4.0 but some still have the previous one 3.8.2 . Well, if I go to Third Party Application section I can’t find any update pending about them. Thanks

PS: also, I think it would be useful being able to update older versions also directly from Global Software Inventory list.
