A couple things come to mind.  Yes, it could be an acutal 32 GB card
that was designed to appear as 64 GB (as was already mentioned).
Another possibility: is it an issue with the "Card-Reader" device? 
Check the card in another computer or with a different card reader, does
it still appear 32 GB?
One other possibility (but less likely IMO), if the card is put back
into Windows machine, does it appear as 64 GB?
