How do I delete ghost inventory?

Hello all,
Introducing myself as a beginner developer.... or kid in a candy store ;-)
I was able to upload a couple of items that should not have made it past your rules. Support chat (shoutout for their help) had me do a manual uninstall in safemode. That did fix this one part I am not getting reloaded every time I open inventory. However, the files are still available in my inventory and so causing experience issues still.
Question: how do I delete the files, or get them deleted? I can provide file IDs until a bigger fix of allowing for a more throughout deletion. 

I'm using quest+link files where created in maximo and blender and psp and blender and just blender and just....

once I get past this - errrr learning Unity next, If anyone wants to mentor me :-D
