Dear @BHD
Sorry that you are experiencing difficulty.
I know you have stated " My WordPress and plugins are up to date. "
To be sure before proceeding could you please make sure:
Wordpress, Lay Theme & Laytheme's Addons are all up to date ?
Any custom CSS or JS that may interfere is temporarily removed.
Any third-party plugins are de-activated to see if this resolves the issue.
Talk soon & best wishes š
Richard
