Yep. That fixed it. Thanks!
I am unable to find any question at this URL.
Thanks. I have put this into /Themes/LeptonX/Components/SideMenu/MobileNavbar/MobileNavbarViewComponent.cs but it does not appear to be overriding the problem code.
It was showing something weird there as the version (2.3.-) so I have updated specifically to 2.3.2 as requested.
However, the behaviour is the same.
