The damage listing on the merc’s sheet has listings for both weapons, and also a static damage number listed in white underneath, regardless of whether weapons are equipped.
I made a video showing this issue as well as the reported issue with the portrait being incorrect as well.

Edit: I couldn’t link the video as the forum kept telling me I couldn’t create a link, even using some other tricks. Remove the extra spaces and it’ll work fine. Apologies.
