CRM WebUI-Filter drop down not having the values at resultlist header column level

Hi All,

We are using Worklist to Search Customer Service requests on the version CRM 7.0 EhP2...Now the issue is when we click on Search button, on the Result list column header level Filter drop down not having values except "Fixed Column Left", "Fixed Column Right'.....We have this issue for only one users and other user able to see all the Filter drop down values.

Kindly let us know what missed out for the user who is facing this issue.

Thanks&Regards
