I think this may be a bug. I created a heart using a shape. Made a smaller one and centered the two together. Subtracted the smaller heart to make a "hole". I then converted it to a text frame and added some text. Looked great on the screen. Selected all and exported. Both the top and bottom of the heart are cut off. Another person in my forum had the same results. I'm attaching my results. Maybe I'm doing something wrong?
