Sharepoint Workspace - Not all views sync

Working on a library in Sharepoint Workspace I noticed that not all views for that Library were syncing.

I found a few posts that said custom views with filters could not sync however this was not correct. All of the views in the library had filters but four of them were missing from Workspace. I looked further and found that the views that were missing were filtering on a date calculation or on a column criteria not being blank.

Removing the date or entering a value fixes this issue and the views sync but this changes the behaviour, so the users may have to do without in Workspace. 


Sorting can also cause the view not to appear in Workspace. Sorting on Modified for example works but sorting on Owner or custom columns.
