problem with custom character arduino 2560

for some reason, my lcd 16x2 display does not show the first line of the "custom character" example, it only shows the character with movingns arms how does it make work?

This is a documented ‘feature’ since the arduino 1.0 IDE was introduced.

Here is one place where you can get some information about how to deal with the problem:
