Seed mix-up?

[Snozzcumber]

Hello! I started some tomato plants from seed on 2/10. I have an issue with one of my varieties. I have both potato leaf and regular leaf seedlings, both of which are supposed to be the Kellogg’s Breakfast variety. I am pretty sure it wasn’t a cross up on my part because I was sure to only have one seed packet open at the time. The seeds were bought from Tomatofest. I have a total of 5 potato leaf seedlings and 2 regular leaf seedlings. This is my first year growing this variety, which one are they SUPPOSED to be?
