Hi there @BromideOxides!
Don here from Shopify.
I'd like to take a look at your setup here to see what might be going on with your manual payment options.
Can you let me know first a bit more about what methods you have added and how you set them up in your admin?
The more detail you can provide here the better we'll be able to check this out together.
If you can also then share a link to your store here, I can take a look to see how that setup you describe is looking there.
I look forward to checking this out with you.
