There was a change recently on Polkadot where staking "locks" are now "holds". This is causing issues with Ledger Live displaying balances. Please rest assured that these are only display issues. You can check your balance using another wallet or a block explorer like Subscan.

One benefit of this change is that a single account can now both nominate directly as well as participate in a staking pool.
