im also experiencing a few quirks trying to do this. right now i have a remote vault (the team vault) added to my personal vault (the local one). i executed

remote vault add

from my local vault. and the dendron sidebar view is not showing hierarchies, and also when i press "command + p", where i can usually search for things in vscode, i am only able to see it for my personal vault and not the team vault that i have added
