That issue has not been apparent to us in our testing nor reported by anyone else at this time, to our knowledge.
It is however, but an interim step to Ver 5.1.8, which is in the queue at Themeforest and which we hope should be approved some time today. Once it is approved, you will see the update theme message in your WP back end. I would suggest wait until you can update to Ver 5.1.8, and then advise.
