$0 captial gain transaction not showing up on form 8949

I received a K-1 where $0 gain/loss (short term) was realized from K-1 Y (basis = sale price). I also have short term transactions from an unrelated 1099-B. In my 8949 I only see the transactions from 8949. I do not see the $0 gain transaction from K-1.

 

I tried to mess around with K-1 by giving it a none-zero gain/loss and it now shows up on 8949. I know $0 gain/loss is not very common in stocks and such (but it's possible say when RSU vest and you immediately sell to cover tax, and hypothetically there's no transaction/brokerage fee involve in which case your basis = sale), but is it correct that they would not be entered into 8949? So is this a bug? I do not think a transaction result in $0 gain/loss should be omitted?
