stretch comes up on buster lb config

[paul@gilbertson.biz]

I have a clean install of Debian buster and when I do "lb config" to 
create a config directory it says "stretch" instead of buster.  
Live-build is package is included in buster so why is it when building 
the config directory it says "stretch".  I tried it on 2 systems that 
have a clean install of buster and got the same thing the config/build 
file says stretch.  What did I miss? Do I just need to go through my 
config/* and make the necessary changes to "buster" for all the files?

Thanks,
Paul
