Trouble with "Feature Choices" in 2024 5e

[Top Knite]

I'm making a custom class for a campaign and I'm trying to make its feature automated like how it is for the sorcerer (Where it prompts you on level up to select 1 of the listed metamagics) but I can't get it to bring up that prompt, it just skips over it. So in the "Features" tab I have the feature listed as "Potential" and under that in "Feature Choices" I have multiple items listed under Type listed as "Potential" to match the Feature's name but on level up it does not bring up an option to select which "Potential" they want to pick and I'm unsure what I am doing wrong.

It is probably a hard coded choice in the ruleset and not a combination of ruleset and data/module.

Indeed, these choices are hard coded at the moment so it won't work with home brewed stuff.
