It's generated with your paper wallet generator. I have the wallet open here in the cli wallet and it definitely is a mimi address. I got stats from the pool with that address and had a stack pending for days. Don't know why a space got added when pasting here.

EDIT: Yeah the space definitely gets added here on bitcointalk. Pasted from miner config to
https://www.charactercountonline.com/ -> no space.
Getting an address in the right format from the paper wallet to the miner is not easy for most users, I now understand the source of the problem.
Let us do this,
Get a GUI wallet, create a wallet & copy the address to the miner.
When is starts mining, please share the address here with us & we will do a huge a Airdrop for the problems you have gone through.
