These all look like pretty straightforward errors to debug.
It's telling you plainly that within the subcircuit (or schem
hierarchy) for U1 there are many components lacking a
set property, or referring to a variable / instance property
that does not exist. Might be properties of U1 instance or
"mystery hooks" in the subcircuit code, but it should be
really simple (we don't care if it's tedious) to just go and
see what's up with, for example, L1 wherever it resides
as an element of U1's design. There's something or there's
nothing for its "inductance" property. Either way you will
learn something about what's unhooked, and it's probably
true of many "fellow traveler" errors too.
