What to do with $0.57 capital loss not reported on 1099-B

Received my year-end report from my brokerage, and I see that there is a $0.57 long-term realized loss resulting from a stock merger.  There is a notation next to the item saying that this is not reported on 1099-B, but that I should report this on Form 8949, Part II, with Box F check.  

 

My question is: do I really have to report this $0.57 loss?  It's not reported on my form 1099-B, and seems nonsensical for me to have to file an extra form (8949) just to report $0.57 in capital loss.
