Describe the bug Smart contract error. I managed to withdraw stkAtom tokens twice

To Reproduce Steps to reproduce the behaviour:

1. Go to https://gala.pstake.finance/stake
2. Select the maximum amount. Click on unstake button
3. Confirm the transaction in metamask.
4. After that, do not close the service page and do not disconnect the wallet. You need to go surf other sites.
5. After 10 minutes, they will return to the https://gala.pstake.finance/stake tab again and the funds will be debited from the staking again. I'm not sure for everyone, but it happened to me. At the same time, no confirmation was required to metamask.

Expected behaviour The user will be delighted! He doubled his deposit + staking!
