Where is my bitcoin going?

My wife and I just had a baby so I might be missing something because I’m tired.

That said,

Why is the balance on my bitcoin changing on Ledger when I haven’t touched any of it in 2 1/2 years? There is no activity on this wallet.

And before I get slammed, most of my bitcoin is on a coldcard, I just happen to hold a small amount on a ledger.

Also, I will not be responding to your DMs.

Thanks!
