Cant combine anymore datastores in datastore2

so im using datastore2 and i have plenty of stores already in the combine but when i try adding anymore its just nil and if i use datastore editor to look and see if its there, its not showing up at all anybody know how i can fix this? is there just a limit to the amount of stores you can have in a combine?

DataStore2.Combine("MASTERKEY","Level","Exp","Health","Currency","Inventory","AttributePoints","Physical","Spell")

Physical and Spell do not appear in here and i dont know why
