Why does ledger btc transactions get split into various wallets?

I recently decided to switch away from a Ledger Nano X and just sent funds from my ledger to my new wallet. I did a test transaction of a $250 to make sure everything was working and ledger sent the $250 to the correct address but sent $2,413.02 to a separate address. I looked it up on blockchain . com and the transaction was from: 2,663.71 to: 250.11 and to: 2,413.02.

When I looked in my ledger wallet on blockchain . com I noticed a chunch of my funds missing out of my original wallet (as shown above), but ledger live was still showing my full amount remaining, and I just sent the rest of the funds over the my new wallet, so I am confident they still exist.

TL:DR - why does ledger sent 2600 dollars when I wanted to send 250? I am assuming there is some benefit, but it gave me a heart attack.
