Search criteria in mobile app

Search criteria in mobile app

I have a DB with approx 18,000 records of names and address's.  When I view a report on the iphone mobile app and I put in a search criteria the results I get are just the first 50 records repeting over and over.
 
For example ..
I have a field called SN (street name). whan I bring up report on monile app I can scroll down and see many records. When I search on the field SN = Main St it returns the first 50 address's on main street and stops. when I scroll down it brings down another 50 address's butthey are the same as previous. this goes on and on. I cant see past 50 records when I put a criteria in.
 
The report works fine on my PC and returns all records wheb I use a search criteria.
