Clause Types failing

Clause Types failing

I'm trying to take my currently PDF contract and turn it into a Zoho Contracts type.  I'm in the process where I have to add the clauses. Whenever I add the first one it goes fine. When I go to add the second clause I get a message;  either it was able to make the clause type but not include it in my contract, or it wasn't able to make the clause type because of an unknown error. Does anybody know what's going on here and how I fix this?
