Counting clicks left in add sizes table is incorrect.

[altf4]

I'm new user of this script, so I may be wrong, but it seems that counting of clicks left in ad sizes table is calculated incorrectly, this is how I see it:

Impressions and clicks received in add sizes table shows total impressions or clicks of each add size.
This is correct.

Impressions left in add sizes table shows impressions left for all of the ads with that specific size plus extra earned or bought impressions.
This is correct.

Clicks left in add sizes table shows only the total of clicks that are left on the ads with that specific size and no extra earned or bought clicks. So whenever I add clicks to that specific size it wont show up anywhere until I add those clicks to a specific ad in that size category.
This is incorrect.
