Custom cursor doesn't work when I open a widget

I guys, I’m trying to change my mouse cursor when I’m located above a button. Unfortunately like you can see to my screenshots the first time I call the widget, the cursor change like I designed, but when I close the widget and I open it again, it doesn’t work and it shows me the default image of cursor(But I don’t know I cannot capture the default slashed circle image in my screenshot but I can see it in my screen). Any Idea how to fix it?

Same problem for me.
Custom cursor work fine when the game start, but after close and re-open my menu the mouse cursor change to the defaut cursor.
