DataSmith in 3D Max 2024 not exporting mesh

I have this project file in 3D Max, and I did export the building shell(3 story hospital building) then I exported the site and then I exported the interior of the building, with furniture and such, for first floor only. THen when I check my folder I only see the datasmith file for the building shell and the site. There is not file for the interiors, I try to export a few times and is the same, I can see the folder with all the processed mesh with the name of the file, but the main Datasmith file does not exist.
Your help is appreciate.
