Logged in after 6 months to my Ledger to check Staked/Delegated Solana and it is not there. It shows undelegated 2 months ago which I never did. Tokens are not showing in my ledger.

Hey guys, I am actually really confused and worried as I have staked/delegated Solana on the Ledger.
Decided to check again this year today and my heart sunk as my portfolio got cut in half as the tokens delegated are gone when I checked EARN . There is a transaction showing undelegated but it is not back in my ledger.
I did not undelegated anything. Where are my tokens? Did someone hack Ledger? I'm so scared that its all gone. Can someone give me some insight of what happened , has this happened to anyone else?
