1.18.2 Polymer unable to remove items from registries (no error) leading to clients being unable to connect

[technobaboo]

Quilt Loader version: 0.17.10 on a dedicated server with a vanilla 1.18.2 client connecting to it.

Mods:
https://modrinth.com/mod/polymer-ports-waystones/version/2.5.1-polymerport.0
https://modrinth.com/mod/polymer/version/0.2.0-rc.4.6%2B1.18.2

Tried on both Quilt with the Fabric API: https://modrinth.com/mod/fabric-api/version/0.67.0%2B1.18.2
and Quilt with the QFAPI: https://modrinth.com/mod/qsl/version/1.0.0-beta.28%2B0.67.0-1.18.2

I expect that the modded items will be removed from the item registry before the client connects so I'm able to connect from a vanilla client, however this only works with the Fabric API. There are no errors in either logs on the server or the client except when the client tries to connect to the QFAPI when I get
