Account schedule Row No Filter wrong result

Hi All,
I found each time I filter the account schedule line in row no. column it result wrong list.
For example, the row no from 0 to 500. The filter is 340..420.
The list result line number 0, 2, 3, 4, 20, 30, 40 ... 300, 400...
Seem all characters in filter criteria 340 and 420 listed in the result list.

Is there any idea to overcome this matter?
I just want to have line list betwee 340 till 420.

Thanks
BHT
