Differences in actual bids

I have some strange in the actual bids

In the overviewpage per category I see the actual bid is € 55

When I click on the auction to make my bid, I see that the actual bid is € 185,–

I also see something strange in bid-history, the bids are not in chronical order. The most strange is the bid of € 150 bij Lenaerts-Kristof

Do you have an explanation for this ? And how can I make the bids equal again in the different views ?
