DrawIo mxGraph: using XmlToSvg loses shape information

Question

I am trying to convert XML to SVG using Java, but it looks like form information is being lost in the process.

Given a simple schedule draw.io:

After running XmlToSvg.java I get:

I saved it as uncompressed XML. I use mxgraph-all.jarfrom mxGraph Repo

Do you know if there are hidden settings for saving shapes and colors?
