You are using a very old version of LO. And you are using the version of
Ubuntu, not from LO directly.

I have tested this:
File > New > Labels
I could switch to the Database "Bibliography" (Standard in LO)
I could select Table "biblio".
I could choose all Database fields.
Works the same way with another database I have connected to LO.
System here: OpenSUSE 15 with LO 18.104.22.168.
Have I understand it right this isn't working for you?
