Thanks for your replies.
Ethan I tried to put an ordered list and an unorderd list in the excerpts and the result was that the Tile showed the Post Title and the first entry on the list. I then tried just typing a numbered list but this just gave me a paragraph on the tile.
Eventually my brain engaged and I typed the list but added a <br> to both the post and excerpt and this achieved the desired result (It does however strip out any formatting spaces! Time to dust off my HTML).
Again thanks for your plugin and reply
Apologies. I am a dipstick. For some reason default menu in parent theme had blanked out. I do not know why?
Will check settings in future
