Hover and visited state mixing

Hi emily9715​  There could be a number of reasons for the problem. Although, I can replicate your issue with a copy of an existing button added to the same slide as the original button (see attached sample) - I never duplicate buttons so I can't offer a reason as to why it is happening.  Note: the 3rd newly created button (not a copy/duplicate) on the same slide does not have this problem. 

If you did not go that route, you could upload a file with just a couple of the relevant slides, it would enable pinpointing the source of the problem. Alternatively, as the buttons in the other training work as you wish, take a look at the button build/states and also check if there are any triggers, functions, different slide properties... attached. Or, if you don't get a resolve, I suggest contacting Articulate Support.
