The missing props issue is an old one and it relates usually to Poser ahving the object files compressed which Vue doesn't like.
Open Poser and run the Uncompress script on your runtime or runtimes if you have many, resave your Poser scene after doing this and they will import into Vue fine.
When running the script remember to check the boxes that says "Delete original files after Uncompressing" otherwise it will keep seeing those.
Poser is a pain with this because even though you do this, each time you add new content it will compress them even if you've asked it not to in your prefs, so my suggestion is to do this regularly to avoid future issues.
I do it regular and have no issues with importing into Vue 6 or 7 Infinite.

Injustice will be avenged.
