Not all Rows get rendered; Out of 5 only 4 get rendered

We are using DHTMLXGRID 2.5;

Problem:
My xml does have 5 rows; But the dhtmlxgrid is dispalying only 4 rows;
in the pagination tab it is displaying “Records from 1 to 5 of 5”

Could any one please let me know hwy this is happening !

Thanks,
Giri

Double-check that each row has unique ID
If issue still occurs - please post the problematic xml

Each row does have a UNIQUE ID;
And this is occuring only if the records are less in number like 4, 6 i.e below 10 records;

Here’s the XML;

<rows total_count="" pos="1">

If this is the initial xml - it is wrong, indexes starts from 0, so it must be

<rows total_count="" pos="0">
