No, not at all - it's just the way the model nomenclature is in certain databases. This "900" class of bikes was known as the Fireblade (from '92 thru '03) and if you dig into its history a little bit, you'll come across further naming nuances.
Another example is when you search for official honda replacement parts via the parts fiche at your favorite dealer / supplier (ie - Honda East Toledo, Ron Ayers, etc). You will find the 2000 model listed as "CBR900RR A" or "CBR900RR AC." The "C" character represents California model bikes btw (difference is due to certain emissions related components).
Also, you might come across the 2000 model listing the "RRY" designation during web searches. Additionally, the 2002 model will show "RR2" and the 2003 will have "RR3."
2000 and 2001 were 929cc but still called a CBR900RR or Fireblade in the UK. There are some 929cc machines registered in 2002 from old stock that was hanging about in showrooms. Mine's a 2001 bike which was registered in 2002. Anyway, you've nothing to worry about!
