GLCD library version 3 (end of life - no longer supported)

I uploaded the "Big Nums" test sketch to my Arduino Uno connected to my KS0108-controlled LCD module. However, what should be on the left side of the display shifted to the right side, and what should be on the right side shifted to the left. Other than that, everything displays perfectly. I double checked the wiring and found no issues. Could someone please help me?

I bought the LCD from this vendor at Ebay.

Here's a picture of what goes on.

Thank you,
