Hello,
Thanks for your patience, Since your issue is kind of strange we need more time to deal with it, As you know we don’t have any codes in our theme and plugins to delete any option from database, So we are 100% sure that it is not something with our codes but since you are our customer and we want you help you to solve your issues we are investigating other plugins that you have like wp rocket and others to see why this happened, Also we can not recover any options hence we do not take back up from customers website, What we are doing now ? 1. Making sure nothing is wrong with our codes. 2. Help to you for find reason of this problem.
I will update you in couple of hours, Your patience is highly appreciated.
Regards
