Random letters after NFT name on Testnet

[vivemateo]

I did maybe reset my remix 5 times, each time re"Transact" and then minting an image to test it. Each new "Transact" I would get a "V" then the transaction version number. Assuming it means new version... but then I got random letters after a dash on the 5th and 6th transaction I tested. I'm hoping when I Transact on the real network I won't get these "V's" or "-RaNdoM".

Example:
1st Transact: NFT NAME
2nd Transact: NFT NAME V2
3rd Transact: NFT NAME V3
4th Transact: NFT NAME V4
5th Transact: NFT NAME - PdpVusXINl
6th Transact: NFT NAME - FvTpuUIEpl
