Thank you so much for using support forum for the query. You can find the breaking news options on Appearance > Customize > Header Options > Breaking News Options and make News per slide one. After that the breaking news will appear one by one. We recommend you to use make the length of the breaking news title little bit short.
Hope, this will solve the issues.
it is already set at 1 title per slide. I think it is a problem with the code. I just added a third title so you can see what I am talking about. The first two titles are running together and the third title is separate.
