Hi Sunil,
do you see the same number in the Data Manager or on the Search UI?
If you have this issue in the Data Manger you have to recreate the named searches.
If you have this issue only on the Search UI than check your call structure according this wiki page:

The parameter should be maintained before the HOOK_URL and it is case sensitive.
Best regards,
Anita
