How to tell when synch is done or is there a problem on my hub?

When I start to sychronize the menu indicates synching is in progress.   While this is occuring I continue to add files to the same folders that are synching.    When it finishes, something I verify by looking that all the files I synched are now on the hub,  the menu still shows synch is in progress.   The log shows the number of files synched but there is no status.    When I change it to synch again the new files are synched.  Is this normal?

It would seem to me that if synch only works on the files staged when synching starts, that the status should change so that one can tell synching is done.
