Incorrect balance litecoin core

I sent myself an amount from another wallet through MW . After I came, I sent it again with the same system. And made a wallet reserve and deleted everything from the computer. A couple of days later, I restored using a copy. As a result, I have twice the amount on my balance, but when I send it, it becomes zero

What wallets did you use?
On what system? Linux, windows, MAC or else? Details my man, details

Windows . Litecoin core. I think the coins have gone back

Transactions are confirmed
