What the heck are these potatos?

I remember in the past, I bought "Asian yams" from my local grocery store and they turned out to be Japanese sweet potatos which turned out to be delicious.

So recently when I saw them again, I bought a few, wrapped them in foil, and baked them the same way. But they tasted disgusting and were definitely the wrong color (yellow/red rather than that vibrant yellow)

So I cut one open raw, and can only assume its a completely different type of potato. Does anyone recognize this?
