This is a developer mistake, not actually a bug. The label "Bait Sprite:" for the Bait item was placed in Misc Flag 2 check box.
It should be placed in functional Weapon 1 above the drop down box in "Action" page.
(not actually a bug) "Bait Sprite:" label placed at wrong element.
Fixed in the next build.
Thank you. It is at the right spot in 573.
