When trying to play a flush the board is counting the hand as 4 of a kind instead. The type of Jack does not seem to matter as I switch between normal, multiple, and steel and all of them show the same. As soon as I swap to a different kind of card in this instance to a King then it works as expected.
Flush with 4 jacks of spade played as 4 of a kind

Four of a kind has higher hand priority than flushes. The priority is shown under Run Info.
