Thank you very much.
We have made the necessary changes.
Within 24 hours we will publish a fixed version through the built-in update.

In the two places where CheckAndFix is called the latitude and longitude are passed in the wrong order. The lines should be:

                bool tlc = positionRange.CheckAndFix(ref tlx, ref tly);
                bool brc = positionRange.CheckAndFix(ref brx, ref bry);
