If an item has injectable morphs, you have to put the channels and deltas info into the main runtime. (The rest of the stuff can stay in an alternate runtime.) For the DAZ figures, this means you need to move the !DAZ folder to the main runtime.

It's become customary to name this kind of folder with an exclamation point first. Some people don't do this, but if the product puts a folder in Libraries, it's probably a good idea to copy that folder to your main runtime.

Not sure about Vue. Sometimes importing is a bit wonky. You might try asking in the Vue forum.
