Ecoinvent 3.7.1 unlinked exchanges

[OliverLyon]

I tried to use the base_setpu_with_ecoinvent function, but there is an error of Invalid Exchanges and shows 1770 unlinked exchanges. The error and versions are posted below. Does anyone know why is it happening and how to solve this problem? Thanks.

Brightway25 1.0.6
Database: Ecoinvent 3.7.1 cutoff.
bw2io: 0.9.dev41
bw2calc: 2.0.dev23
bw2data:4.0.dev59
