Suddenly, when I opened Dazzle this morning, my DC bar code went from being the usual with "420 xxxxx", the x's being the buyer's zip code.  This morning, my DC's look much shorter without the "420 xxxxx" before it.
 
Does anyone know what happened?  I seem to remember a year or two ago, via an email from endicia, we were told to check mark something certain to do this.  I've looked all over and can't seem to find what it is.
 
Can someone help?

Thanks for that - I'll keep it handy for future reference.  When I opened it this morning (same file & everything), everything printed as they normally do.  I don't know what happened!
