Sorry if this already been reported. I've searched and don't find anyone mentioned this. Here's the scenario:
1. Clicked "Withdraw blood this Item" (missing 'using'?) to use the bag. Worked fine.
2. Wanted to use another bag. Click "Use another" link, but nothing happened. So I clicked "Withdraw blood this Item" again. Worked as well. BUT unlike using bottle of beers, the last log from previous event is not removed and still displayed. And 'Use another" link still does nothing.
