Qamar;
From the image it appears that the issue is with the template file you are using not matching the form itself. Do you notice how the marker dots (in red) do not quite match up with the shaded circles on the form? That seems to be because the template tells Formscanner to look in the wrong places. At first that error is not too large and there is enough overlap with the shaded area that formscanner still sees the mark, but soon it drifts too much and no longer sees the marks at all.
This mis-match seems to get worse going left to right, so one possible issues is that the printed forms are enlarged compared to the image used for the template. Another might be an error in the template, such as telling the program there are more columns/questions than there actually are, or causing the program to expect the columns to be evenly spaced when they are not (for example if the "Award sheet" digits were entered as a single group the template would assume equal spacing of all columns). Without knowing how the template is organized it is hard to tell.
To solve the problem you might need to make a new template file that matches the size and/or corrects the error, or adjust the scanning to fix the distortion if it is a enlargement issue that is causing the lack of correspondence.
I hope this is helpful to you!
