SWR meter not displaying during transmit

[KL7MJ]

I just built my trusdx this weekend, and loaded the beta firmware (I figured that I might as well load the latest).
Anyway, the only time the SWR meter is displayed is when I transmit in CW using the straight key setting. When I use the iambic setting, or USB that area of the display is blank.
Is that normal behavior, a beta firmware issue, or something peculiar to my rig?
Thanks.
