Document structure colors not displaying correctly in Trados Studio as created in the file type

Question

I have created an XML file type (Embedded Content) that works perfectly for projects created in Trados Studio 2022. This is what I want it to look like:

When I import the file type into WorldServer and create the project there, this is what it looks like instead when I open the package in Trados Studio 2022:

The color information in the document structure is lost and the Advanced Display Filter is blacked out. When I look into the project settings parser rules, I see that the color information should be being applied:

What can I do to fix this so the color coding works properly everywhere?

Hello Michael, in the meantime, I have reproduced the behaviour and I have filed it as defect CRQ-33597. This could be related to the WorldServer Components where after the conversion of the WSXZ package to a WorldServer Studio package, most colours are no longer visible. In my tests, some colours are preserved, but most are not. This is reproducible also with the XML2 File Type and WorldServer 11.8., by the way. 
 If you want to be able to follow the progress of the defect, please submit a support case and I will link it to it.
