Hey Michail. No. It's like what I said. I had 1 address in my CoPay wallet.
I send 0.001 from it. But what CoPay did: It sent the 0.001 + 0.05 to a new adress which contains now to my wallet.
The 0.05 are still mine. But now I don't know how to get the 0.05 back to my big address.
Which is what I said. Change address.
But, without seeing the transaction ID, it's hard to explain/guess. You're welcome to message me directly to work through this, but asking in a forum without any information is simply going to get a lot of guessing done. What you think and what I think are simply guesswork until we're both looking at the same thing.
One more try.
1. I created Copay wallet. It contained 1 address (AAAAA).
2. I sent 8 BTC to AAAAA
3. Then I sent 0.001xxx BTC from AAAAA to Byteball
4. What Copay did:
a) They sent 0.001xxx BTC from AAAAA to Byteball
b) They sent 0.05 BTC from AAAAA to BBBBB (I never did this transaction - it's done automatically for what ever reason)
5. Now I have two addresses in my Copay wallet (AAAAA with 7.949 BTC + BBBBB with 0.05 BTC)
6. How do I get the BTC from BBBBB to AAAAA?
I hope this makes it clear.
