Yeah I found the problem, in first transaction I used too low gas and was rejected, so I didnt get coins, but pos state reset. So when I tried again there were nothing to mint. Will know for the next time.
Don't call mint function. You're robbing Yourself and Your transaction can be rejected because of low gas. Instead just send 0 (Yeah ZERO) POS from YOUR WALLET to YOUR WALLET(same one). Leave gas limit as it appears but lower gas price to whatever you feel like (assuming You are using MEW). Here is my tx with 0.6 Gwei price:

Also Your balance will update in Etherscan after some period (check after ~15-30 mins), it's not immediate.
I can confirm that you're my man, used the same thing you just mentioned & was updated in like 7 minutes only.
Used 0.7 GEWI only & was resolved in couple minutes (like 5 minutes) than 2 minutes later i got my Minted PoS (just like the calculator said.
Thank you man you're great,
you should contact PoS token Dev to add this Mint Guide to his OP.
