Missing connections after converting vsd to vsdx

After importing vsd file to vsdx it loses some of its connections.

In addition to vsd file and a screenshot of missing connections, I’ve also added a screenshot of xml files comparing convertion done by the aspose lib and by Visio itself where the former lacks more than half of the connections.

vsd file and screenshots:
lost connections.zip (980.9 KB)

The file was converted using this part of code:

File file = new File(PATH_TO_VSD_FILE);
Diagram d = new Diagram(file.getAbsolutePath());
d.save(file.getAbsolutePath() + "x", SaveFileFormat.VSDX);
