When you duplicate an object make sure you look at what it is named. I had duplicated a "repeating" button, but the new button should not have had repeating on it.
After I did an "update repeating" my new buttons vanished. I of course did not see this immediately. Fortunately I did notice today and thanks to the Xarareg programme I had save backups.
So, I restored a backup and removed repeating from my buttons and now it works as I intended
