Cant click on buttons in widget?

I have made a simple widget that uses a switcher to change the pages. The button to go to the next page doesn’t even register with the mouse (not highlighting or clicking).
Is this just a simple fix?

Thanks, i fixed it somehow. Something to do with the buttons being in a overlay . Thanks
