FLP on EP remove duplicate tiles when disable Personalization

Hi All,

We have some iviews assigned different roles , and this different roles can be assign same user . So that users have access to same iviews from different roles.

So our user sees the same ivews duplicates  in the same category .

So my question is how we can remove duplicate tiles from FLP ?

Note : we are using disable option for the personalization on portal .

Portal version : SAP NetWeaver 7.5 SP1

Thanks .
