Not shows all contracts types for to create an contract.

I created three Contract Types:

- Type1 - No Allow lines;

- Type2 - Line Class: Project and Allow lines;

- Type3 - Line Class: Service and Allow lines;

I need to create a contract with the contract type " Type2 - Line Class: Project and Allow lines", but it only shows the contract type " Type1 - No Allow lines", and it doesn't show the other two contract types.
