@luckyhusky I think it's because 1. I use a lot of scientific term, most of it is justified but I think I should trim it down a bit. 2. It is read from right to left. I probably fix this by making the right text placed higher than the left text to make sure how people will read the text. 3. I use justify text which may make a lot extranous space between words. In hindsight I should've just used align center
