subcategory disappear

Hello! I use BeautySecrets and today suddenly all the subcategoreis disappeared from the menu,where they were before. I didn`t do anything for it. Is it possible to correct and what can I do for it?
Thanks!

Hi!
Probably, you have to customize your menu on page Appearance => Menus.
Here are the intelligible instructions:
