I think I fucked up learning my wallet and using Monero

I have been slowly buying Monero and sending it to cold storages but I recently just checked my cold wallet and noticed my last 2 transactions never made it to my cold wallet. It shows sent on the CEX side but not in my GUI wallet. Am I not supposed to use the same wallet address or was I robbed blind?
