Table filter not working

In an application module out of the box feature of filtering tables doesn't work for all the view objects for some reason

For the same view object filter works fine in another application module..should check why this happens 

Timestamp datatype in View Object gets the date and timestamp ADF

Normal Date type for an attribute in View Object always shows hours as 00:00:00 though you have mentioned yyyy-MM-dd 'at' hh:mm:ss a in the control hints of the Attribute in VO

a is for AM/PM
hh is for 12 hours / HH is for 24 hours time
