Sound like you have a question about PowerPoint, this group is for
Publisher, so reposting there might yield more/better help.
We (or they) would need more info to help.
Are the words all in the same text box?
PowerPoint doesn't have a lot of formatting options for text (compared to
Word or Publisher), but depending on the version, you could check the font
formatting to make sure the font is set to Regular with no features ticked.
Have you tried changing fonts?
