The function below should do it:

const response = [];

for (const item of items) {
  const issuedItem = item.json['Issued Items'];
  const returnedItems = item.json['Returned Items']
  const toDeleteIndex = [];
  
  for (const returnedItem of returnedItems) {
    if (issuedItem.includes(returnedItem)) {
      toDeleteIndex.push(issuedItem.indexOf(returnedItem))
    }
  }
    
  for (const index of toDeleteIndex) {
     item.json['Issued Items'].splice(index, 1)
  }
  
  response.push(item)
}

return response
