I can see the problem, but its really hard to tell by only seeing it.
2 questions:
1. Are you facing issue with only these 4 auctions? If yes, then lets say you “end aution” from admin dashboard -> ultimate auction ->manage auction -> live auctions-> end auction….and add new ones then do you get same problem? I’m trying to see if that is it reproducible & whether you have a workaround.
For further debugging, I would require your admin credentials since I could not reproduce same behavior on my side. For confidentiality you can use my contact form to pass on credentials: https://auctionplugin.net/contact
2. I also notice that you are not using “incremental value” when adding auction. If your intention is to sell a fixed price product then just enter “buy now” field while adding auction & you’ll have fixed price value & no biding. If you are looking for bids then do enter incremental value otherwise your bids wont increase by default.
