Thanks, I understand now, i fixed it by change the order of filter.

The real problem happened when we have same filter like in Lazarus  (*.pas,
*.pp, *.inc) and if we set the DefaultExt to .pp it will return .pas as the
first filter extension, but i think Lazarus fix it manual, for me i changed
the order depend on the current file opened, i moved the extension to the
first.
