Unable to select "Plugin" as a distribution method

Summary

I have migrated my plugin to Fab from UE Marketplace using the migration within Fab. The migration automatically moved everything over as expected, however in the “Unreal Engine” section I only have the option to distribute as an “Asset Package” or “Complete Project”.

What type of bug are you experiencing?

Publishing

Steps to Reproduce

Login.
Edit the listing (Formation System v2)
Click “Unreal Engine” on the left under Additional Files
Scroll down to “Distribution Method”
Fail to find “Plugin” as an option

Expected Result

I expect to have an option to distribute my plugin as a plugin. The review process seems to agree with me.

Observed Result

There are only two options under distribution method: “Asset Package” or “Complete Project”.

Platform
