In the past few weeks I've purchased two of these light meters and both have obstructions over the finder screen and the spot readout. I've attached a picture of the first one. Notice the "10" is cut off at the bottom and between the numbers and the spot circle, a black line is obstructing the viewfinder. The same thing is happening on the second one I bought, but the obstructions are angled the other way.

Has anyone else seen this? Any fix for it? Thanks.
