Sub Report with space issue

Hi,
I am new in this area and i need some help with the subreport.

1. i have a report with 2 columns divided by the column only ( link ), earning and deduction.

after that i used multiple section and it is works fine but there are some space left on the above section as i have some other static text that's why..

Color boxes are the section.

deduction looks great but earning has white space below basic pay and i want to remove.
Sub reports are
1. Allowance
2. that add pay * 1 (section)
3. advance salary on deduction section

all other fields are static..
