1) If you have a balance issue, there is a tool for advanced users.
Please take look at this article.
2) You sent Litecoin (LTC) to Bitcoin (BTC)
You can take a look at this thread for possible solutions. Also, you can try to get in touch with your exchange or your wallet provider for more help.
3) You sent Litecoin (LTC) from a Legacy address to a Segwit address (and vice-versa)?
They do not have the same address format. Please send from Legacy to Legacy and from Segwit to Segwit. Please see: How to receive Litecoin payments? Where can I find my Litecoin address ?
4) You can not send your Litecoin (LTC) from an exchange to your Ledger wallet.
It seems that the sending address did not have Segwit activated at the time of your transaction.
So some explorers and wallets don't recognize the new address version of Litecoin. You can convert it using https://litecoin-project.github.io/p2sh-convert/
Both addresses are Segwit addresses, and both addresses are the same, just written with a different version. If you are unsure about how to proceed please get in touch with your exchange or wallet provider.
