Scroll area display problems

We have a scroll area in level 1 where the occurs count is set to 20. When the page displays in PIA, if there are less than 20 rows, the display is correct without any errors. If there are more than 20 rows, by default the page shows 20 rows and the display is correct as well.

However, when 'View All' is clicked, the alignment is messed up as we go down the page. The plus and minus buttons are not aligned correctly, and in the last row, they completely disappear. From what we have observed, this issue occurs only when there are huge number of rows and 'View All' is clicked. For e.g. if there are 80 or 100 plus rows, and we click 'View All', for all the rows situated around the 40th or 50th position, the alignment will be messed up.
