The fact that the wallet after leaving it and then entering it each time changes the address of the coin - is this normal ??

I can not drive into the purse my first address on which came a coin from the pool

What does he look like? I went in and looked. Each opening of the purse-address of the coin changes. I spent 3 times, each time a new address generates a purse.

 
The purse is synchronized with the network, but the purse address is different.
Of course, there are no coins

 I worked at http://kmc-pool.ddns.net/#.
My wallet address is KmhyoJrWQBUCEU3ifNjfXSJv3SXQFsMTcKLgvKNNs9bvULt61CRQJxhchAuh47BnhZ2oDHppRyrFtMV jHdrGumf246w3xHp
The last payment of 23.6 coins did not come.
I closed and then opened the purse and changed the address of the coin
I closed the 3 times and opened the purse and the address was different every time?
 The coins were gone. The coin's address is different after opening the wallet ...
