Bug on the IOS app?

I've just started using Voice Log, a very nice feature.

I added a number of items to my lunch and it went very smoothly.

I missed an item, so i tapped "Log More." Nothing seemed to happen and I tried it several times. It turned out it was adding it to a different meal (dinner instead of lunch), even though I was looking at lunch.

I tried it again several times, and it always added it to dinner instead of lunch. Am I missing something, or is this a bug?
