Missing Features after exporting DTM to XML and then re-importing

Hello,

I’ve exported out our DTM to XML using LandXML Translator.
I then Import that XML to verify that it had been properly exported.

However, when I compare the XML to the original DTM, the XML is missing a large amount of breakline features.
Below, “Gen-West” is the original DTM and “Gen-West1” is the import of newly created XML.





Thinking that it may have been a problem with the DTM, I’ve tried creating a dummy surface, copying all features of the original DTM into that, and then exporting the XML, but still missing a lot of breakline features.

Would anyone know what the issue may be?
I am under the impression that the LandXML Translator was to export All features.

Any input you have would be greatly appreciated!
