I am experiencing the opposite problem. In PPT my first line is formatted with NO bullet. There is a return after the first line and then the third and subsequent lines are formatted as bullets. Looks fine in PPT but, when I publish, a bullet is ADDED to the first line.
I've had some success by reformatting the text of the first 3 lines, but it works for some slides and not for others. I worked with the Masters but can't seem to isolate the problem to a specific Master.
We recently moved from Office 2007 to Office 2010. This problem never happened before the upgrade. We are making updates to courses that were originally done with PPT 2007. Is there a problem with PPT versions here? I'm using Articulate 9.
