Setting selectable in rbinfo file is not working

Hi,

I have updated the .rbinfo file adding some more entries. I am setting some entries as non selectable  to avoid it to be visible in the dropdown.Entry updated in rbinfo is as below:

      Test.abbreviatedDisplay=0033

     Test.display=Test

     Test.selectable=false

     Test.value=0033

Even after setting it to false, I am able to see it in dropdown. Anyone has answer to this..

My windchill version is 10.1 M030

Thanks in Advance..
