Uncollapse the "Stakingrewards At ADDRESS" menu that just appeared on the left of remix, click "exit" and confirm your transaction. If an additional gas menu pops up, like on AVAX, then fill both gwei fields with 225 and then confirm the transaction in Remix, and also in MetaMask (ensuring the gas isn't too expensive). This should pull your LP out. You're finished! Head to the pool at app.elk.finance and withdraw your liquidity.
