I don't know what "another wallet address" means? I have only 1 wallet and I signed in for the test.bank just once. Is this that:

Balance in the bank is 108.57953312, but balance in the wallet is:

The question was why mined coins didn't appeared on the bank balance automatically, and instead I had to send them manually by "payment to myself"?
That just seems weird if the wallet and the bank are syncd. The next question is, if the balance in the bank is 108 and the balance in my only wallet is 58 - where is that other wallet that contains remaining 50 that is also syncd with the bank? Thanks

The coins from the wallet to Minexbank account transfer automatically. You just need to wait.
You don't need send them manually by "payment to myself''.
Today during the day we will solve this problem.
