[Plugin: Kadom Ads Management] White border on Ads

Just installed Kadom ad managemebnt and it is really exactly what I would need. I had no problems setting up ad zones and campaigns. The ads display just like they should on my blog BUT

It seems that to all banners i add, a white border is added to the left and bottom of the banner…meaning that banners get cut off exactly 10px at the right and top, as the banner is basically “pushed” to the top right by the added white border.

I have played around with all settings on the sidebar widget (tried different settings for the border, amount of ads displayed etc. )…same result.

Also I double checked that the size of the banner in the ad zone settings and the actual size of the banners i added are correct… which they were. Still, all banners are cut by 10 PX just like before at the top and right.

Any idea what could be the cause?
