Hi Simon,
It appears that you’re using 4 icons on your menus, of which three are Font Awesome, while the third one is Dashicons. Try to use the same icon set on all menu items to fix it.
Let us know if it works.
Hi Hardeep,
Thank you for the fix. Previously using any one of the other 3 icons also gave the same result, however, it is fixed now. And I was unaware of the cross between Font Awesome and Dashicons, so this helped a lot!
Thank you for your time once again.
Regards,
Simon
