Cannot add items to parcels on PF2e ruleset with version 1.9

[KazutoDM]

This broke recently and has blocked me from adding items to parcels with this extension active on the PF2e ruleset.
I have confirmed that the issue happens with only this extension active and is fixed once deactivated.

I noticed something I missed in the code (they renamed something) and after the change I'm not seeing this issue. So hopefully v1.9-hotfix.1 sorts it out for you, keep me posted!
