All my variables in my widgets are not editable - why and how can i make them editable ?

But i see people have on all those widgets the eye icon On and on the tutorials they even say explicitly turn this on so this will work later on. i have the same widgets with the same variables but mine are all non editable and on the video all are set as editible eye icon is on. i recreated just for testing a new widget and testet it again with no success then i revisit my old 5-6 widgets that i had and all are non editable varibles as well in there. Then i asked a friend if he could not recreate this and it came out that all his variables were by default on with the eye icon open. here is an example from 1 tutorial @ 4 min and 20 sec Unreal Engine 4 Tutorial - Skill System Pt.5: Perk Points - YouTube

and here is my widget

in fact i have like around 10 widgets in total and all are non editable and my friend tested this as well he created a fresh widget added a button set it to variable and in the graph it was set with an open eye icon as editable.

P.S. here is the screenshot of my friend (after creating a simple button its editable in the graph and to me i cant add a button that is editable no matter how many new widgets i create)
