Is it a problem if a 1-wire sensor is not "allocated"??

I’m setting up my first 1-wire weather station. The maintemp, humidity, barometer and solar all appear to be reading properly. However, all the sensors except for the solar are listed in 1-wire setup as “allocated”. Is the solar sensor reading properly if it has not been allocated? Does this matter? If it does, how do I get this to happen? The solar is on a combined temp/hum/solar Hobby Boards unit.
Thankyou
