Problems with Widget Blueprints Events

Ive made a reusable Button widget, however once i place it into my Menu Widget i cannot use the events, OnClicked etc, this worked for me in the past when i was using version 4.12.5, i am now on 4.17.2, i have tried adding a button straight from the Palette and it shows the events drop down, so i tried to make another Button Widget from scratch, starting with doing nothing other than placing in a button, and even then there is no events drop down, is there some difference in the versions that could be causing this or some other problem?
Thanks in Advance
