Here's a step by step on what I did from the beginning, maybe it will help.
1. Run Bitcoin core 2.Uncheck prune storage 3.Create test wallet(which gave me the wallet folder)> Go to bitcoin core data directory>test wallet folder> rename wallet.dat to wallet-test.dat> copy old wallet.dat and paste in test wallet folder 4. Let Bitcoin Core synch 5. Close BTC core and rerun 6. File> Open Wallet which only shows test wallet.
The "
wallet-test.dat" is in the "
test wallet" folder so it won't be included to the open wallet selection menu, it should be outside that folder, but inside the 'wallets' folder.
The folders inside the 'wallets' folder are considered as 1 wallet and it will use the wallet.dat file inside it.
If you want to use a renamed wallet.dat file, you should paste it in 'wallets' folder's root, not in the other folders inside it.
Only 1 wallet shows in the "
Wallets:" drop-down menu because you've replaced the test wallet's wallet.dat with the old wallet, so the one's recognized by Bitcoin Core is the old wallet.
I hope that you've closed Bitcoin Core when you're swapping the wallet.dat files or there will be issues during the scan process of those wallet files.

you said you've watch video tutorials so they must have mentioned it)
