Question

I ordered this tongue drum, and full transparency I did not look closely enough at it when I ordered it.

It was labeled an 8 note c major drum. I assumed it would have one full c-c scale. It does not. What it does have is A3-C4-D4-E4-F4-G4-A4-B4 Looking back at the listing it is labeled as such so it has to be on purpose.

Was I wrong to assume? Most of the songs I look up to play need that higher c in a full scale. Am I missing something music theory related that I just don’t know about? What’s the purpose of having a lower A instead of the higher C?
