due to as an ADJ?

[AngledLuffa]

This looks incorrect:

# sent_id = w01020018
# text = Due to the shared climate, geology, and access to the sea, cultures centered on the Mediterranean tended to have some extent of intertwined culture and history.
1       Due     due     ADJ     JJ      Degree=Pos|ExtPos=ADP   5       case    5:case  _
2       to      to      ADP     IN      _       1       fixed   1:fixed _

normally it looks like

# newdoc id = n01123
# sent_id = n01123010
# text = But Cotton’s dark deeds did not occur due to some sort of compulsion to kill.
9       due     due     ADP     IN      ExtPos=ADP      12      case    12:case _
10      to      to      ADP     IN      _       9       fixed   9:fixed _

Can you ever use due as an adposition without accompanying it by to?

Our guidelines say it's an adjective. https://universaldependencies.org/en/dep/fixed.html
