Modular features missing from shipped build

Hey everyone!
I have a project that uses Modular Gameplay Features, with Game Features that have PrimaryDataAssets in them. Logic in the base game loads the assets using the asset manager. I configured the primary assets in the project settings, and in-editor everything works as expected.

When I package the game, regardless of profile, it looks like none of the primary data assets is getting cooked. The only way I can get it to work is if I use the “Specific Assets” option in the asset manager settings.

Using “Additional Non-Asset Directories to Package” and “Additional Asset Directories to Cook” didn’t work either.

Any ideas?
Thanks!
