Brave Wallet accounts after connecting Ledger

After connecting my Ledger to my Brave Wallet, I noticed several accounts with crypto in them that I don’t remember purchasing. Here is an example with $42.64 of Matic. What is the meaning of these ‘accounts,’ and can I access them?

Hello! If these addresses are on your Ledger, they are yours. You can manage and view these accounts on your Ledger Live app as well.

Thank you for your reply. Is it possible that these accounts are showing the wrong information? I can’t seem to access these accounts on my ledger and I notice that the account’s name ends in 0x. It also shows the account as having $0 in this screenshot, even though when I click “Assets” in the “Portfolio” section, many of the coins have a balance - even ones I don’t remember buying.

It seems I could solve this by trying to sell using Ramp through the Brave wallet, but the Brave wallet can’t connect to Ramp. I am having the same issue with Aurora where it is saying ‘Connection can be declined if a previous request is still active’.
