One of the PowerPoint annoyances is that bullet point paragraphs are not aligned properly when overflowing to the next line. It's easy to fix.
Display the ruler (view menu), select the text, and move the little markers, leaving the top one to the left, and the bottom one at the desired indent. (See the image to the right).
That bullet points are NOT the main design concept to make PowerPoint presentations is clear, but a completely separate subject.
