Default [6.24] iXML metadata : track information missing for multichannel files (FIXED)

Hi,

Reaper don't show me all iXML Metadata : Track information is missing for all multichannel files.

Missing in the "Take Media Source Properties", missing in API GetMediaFileMetadata to.

I think I understand why.
In multichannel files, iXML gives track information like this (extract of an ixml code):
Code:
<TRACK_LIST>
<TRACK_COUNT>6</TRACK_COUNT>
<TRACK>
<CHANNEL_INDEX>1</CHANNEL_INDEX>
<INTERLEAVE_INDEX>1</INTERLEAVE_INDEX>
<NAME>Perche 1</NAME>
<FUNCTION></FUNCTION>
</TRACK>
<TRACK>
<CHANNEL_INDEX>2</CHANNEL_INDEX>
<INTERLEAVE_INDEX>2</INTERLEAVE_INDEX>
<NAME>Perche 2</NAME>
<FUNCTION></FUNCTION>
</TRACK>
<TRACK>
<CHANNEL_INDEX>3</CHANNEL_INDEX>
<INTERLEAVE_INDEX>3</INTERLEAVE_INDEX>
<NAME>ORTF L</NAME>
<FUNCTION></FUNCTION>
</TRACK>
<TRACK>
<CHANNEL_INDEX>4</CHANNEL_INDEX>
<INTERLEAVE_INDEX>4</INTERLEAVE_INDEX>
<NAME>ORTF R</NAME>
<FUNCTION></FUNCTION>
</TRACK>
<TRACK>
<CHANNEL_INDEX>5</CHANNEL_INDEX>
<INTERLEAVE_INDEX>5</INTERLEAVE_INDEX>
<NAME>Musique L</NAME>
<FUNCTION></FUNCTION>
</TRACK>
<TRACK>
<CHANNEL_INDEX>6</CHANNEL_INDEX>
<INTERLEAVE_INDEX>6</INTERLEAVE_INDEX>
<NAME>Musique R</NAME>
<FUNCTION></FUNCTION>
</TRACK>
</TRACK_LIST>
And Reaper only show the last track info :

I think Reaper doesn't understand this information because it finds the same tag several times (CHANNEL_INDEX, INTERLEAVE_INDEX, NAME, FUNCTION). And keeps only the last one.

iXML metadata ar important for postproduction works.
Some recorder like Aaton Cantar X3 don't provide tracks infos in BWF metadata, only in iXML metadata.

Thanks for reading me
