orcad capture 17.2: Bus has no name and therefore defines no signals

Hello,

I was doing a DRC and got "Bus has no name and therefore defines no signals". How do I fix that?

I put a bus with bus entries on the bus and wires with net aliases SCL0 and SDA0.  If I double click on the bus it shows Net Properties with Name N149...  What's wrong, how do I fix?
