Hit percentage on "HUD" always snows 1%?

This bug seems to only effect certain soldiers, and once it starts it doesn't go away. I had a soldier with 3 enemies in sight. Hovering the mouse over the alien heads in the bottom right showed all three with 1% hit chance. I move to a closer firing position, and still 1%. I put him in overwatch and finished the other soldier's turns. I ended up finishing the mission with without using him, except for overwatch because it never showed anything over 1%.

The next mission, with the same soldier, no matter what or where he was, the alien heads were showing 1% chance to hit. I decided to aim at one anyway, and when I do go into aim/fire mode it shows in the screen what I assume is the correct percentage.

Yesterday it starting happening with another soldier, except the this one always shows 99%. It was only effecting those two soldiers, but today it seems to be doing it to others, except for the others it changes. One time it may show 60% on the lower right, but 30% when I go to take the shot, or it may show 30% in the lower right, but be 60% when I take the shot.

It's not a game breaking bug, but it is very annoying to have to go into firing mode every time to see what the actual shot percentage will be rather than being able to see it at a glance in the lower right.
