the CL on cardboard is correct, they just label it as Prime Level 1. it also matches what is in beckett. so the Prime (level) 1 through 4 have different Mem's w/ different amount of cards and 5 is the same only it has variations to go with it. the CL isn't difficult to make for it, just have to add the teams to go with it
EDIT- the reason you're probably not seeing the names on the CL align on cardboard and becket is that Cardboard just goes alphabetically and beckett does too, but puts the 3 letter alpha numbering at the end of the CL.. but they are there
