Exception type: CrmArgumentException , Exception message: Cannot add attribute from of type partylist in a condition , advance search phone call MS CRM 2011

while i was doing advanced search i got the below error

when i tried in a fresh organization, i donot see From as searchable.
while investigating, i got to know that the From field in Phone Call, EMail was made searchable.
both are partylist and by default those are not searchable.
so i changed to non searchable and its done.

how it come as searchable?
if you go to fields and select more than one and do edit, then you can edit...
initially searchable is disabled and read only as below..

then i made bulk edit as below

then see the below screen as the field enabled and you can select Yes or No

below is the event viewer details
