[Blurry]

Hey, I'm having a little trouble when posting auctions. For example, if someone posts a Heavenly Shard for 90gbid, 100g Buyout. When I put mine up, it will undercut the buyout by a few coppers just like I've set it to. but the 'bid' part, stays above 90g.

When I go into Config>categories/groups>general price settings (undercut/bid). I've tried sliding the % to 30%, 60%, 90% but nothing happens. As i understand it, that slider is supposed to set the bid as a % of the buyout. Is that not correct?

Am I doing something wrong or is it bugged/incompatible with something?

EDIT: I've been fiddling around with it more and I've only managed to once get it to post the bid price approx 10g below the buyout which is what i wanted. But after that, everthing else just posts with identical bid and buyouts :\
