Why does square decline legitimate checks

[Ceo4jnfg]

So I have tried to deposit 2 checks into my new square account and both have been declined. Reason says that a problem with the check has been detected. One of the checks is a government check from the state of Illinois. It is Ludacris. What kind of problem could this government check possibly have?

Hello @Ceo4jnfg - Thanks for reaching out. I know this isn’t convenient, and I want to help. 

To clarify, is the other check a government check or a standard one? Do you know the exact error message you got? If you have a photo, that would be helpful.
