Project Server 2013: TS Approval history wont' show filtered by Resource name

After migration to Project Server 2013, I have found several bugs that have been confirmed but not yet resolved by Microsoft.

One of them:

For timesheets in approval center, while applying "Resources" filter and fetching timesheets with "Resource Name", project server 2013 does not show any timesheets

As of October 2013, 

RESOLUTION:

 -  Resource filter issue in 2013 is reproducible with latest CU in-house.
 - This looks to be a known bug in project server 2013 and we have already filed an internal bug.

 - But, as an alternate solution, you can uncheck both "Date" and "Resource" filters and then use resource name to get the timesheet.
