agilent ads2004 layout to excellon file problem

Hi, everyone. Right now I am going to use the gerber translator to convert the layout from agilent ADS layout to gerber and excellon drill file.

Everything is OK for gerber file conversion, but it seems there is some error for the excellon file generation. I cannot specified the format of the file but only the default 2.4. And the other problem is that I found actually the excellon drill file output is 2.3 instead of 2.4. I am wondering whether it is a bug of the translator, or I missed something in the conversion setting?

Thanks in advance~
