Icon missing on the screen layout

Screen Layout

Screen Layout tree

Hi, does anyone knows why I can’t see the icon on my screen layout? On the screen layout tree, there are two icons but on the screen layout, I can’t see them.
I have tried to view it on google chrome and Microsoft edge but it’s the same on both. This has only happened for me recently, Very hard to work on the front end without seeing the icon.
someone would help me?

Check the button’s properties >> advanced properties >> visibility
Make sure it is set to ‘true’
