It appears as though the designer mock-up tool is shifting my uploaded design to the left (looking at screen). This only appears to happen with the Tan and Dark Chocolate colors. When I upload my design and select (for example) the blue shirt, it's centered as it should be, however when I change the color to Tan (without uploading design again) either the design itself or possibly the mock shirt image is moving and making the design look completely off-centered. This is preventing me from using these two colors (Tan and Dark Chocolate) because I'm assuming this is how the design will be placed on the shirt when printed.

Here are snapshots of a yellow shirt and tan shirt directly from the design page.

sorry, i'll try that again..

Notice the letter "U" is nearly directly underneath the tag on the tan shirt which is further over than on the yellow shirt.
