I sent a small amount to BTC, the explorer shows a larger amount, sent to a different address, Why?

I liked it, to use a single address, to check my BTC, but after withdrawing a small amount, I notice, that he took about three times that and placed it in a different address. Ledger Live has the correct total (probably with the xpub), but the web explorer, which I use for the specific address total, is wrong now. Why does he do this, and there is a possibility, from the additional addresses back to the “Main address” to send?
