Bug With Charge Icons

There are 2 screen snapshots below.  The first one shows "good" behavior when moving the cursor over any of the first 5 (counting from the right) Charge icons.  The second one shows that the sixth charge icon cannot be accessed, either by moving the cursor over it to display the hover text or by clicking on it.

 

I cannot capture the cursor position when I take a screen snapshot but, trust me, it is hovering over the green Charge icon.
