Sorry for the silly question. Here is the answer if anyone has the same problem.
When I created a bus "downstream", I incorporated the same signal name from two different buses. These were essentially the same function for two different components, if that makes sense. Essentially, I grabbed signalName from componentA.signalName and also signalName from componentB.signalName. When I created a bus using these two different signals, but having the same signal name, Simulink added (signal 1) and (signal 2) as a suffix to the signal names to make them unique signal names.
After I changed the signal names before creating my new bus, Simulink removed (signal 1) and (signal 2) as suffixes because the names were now unique in the bus.
