My issue is with that transaction another output is produced the one to the wallet is segwit (P2WPKH) and another Standard (PKH) which is about 10x the original btc amount sent to the wallet is now a unconfirmed transaction.
Thanks
The recipient address must be P2WPKH, and the other TX you see is the remaining balance of the chosen UTXO sent back to a change address, which is probably the standard legacy PKH address.
10x back to change address because the default setting chose a larger UTXO, so it is
Input UTXO = Sent Amount + Change + Fee, which is irrelevant why the TX is unconfirmed. And yes, it is due to the low fee but not that low, since your TX will be included in the block if

So wait for a while, and everything will be okay soon.
Why is this happening? Can I clear it? I was thinking using help > clear all unconfirmed.
This won't cancel the transaction because technically you can't cancel a bitcoin TX once it's broadcasted, what you can do is RBF but it is not necessary IMO and clear all unconfirmed, it will just clear the unconfirmed TX from history, resulting in wrong balance.
