Post title is showed 2 times on mobile application

Hi Sakin, I've got one small bug on the mobile application of my blog (laqueebecoise.besaba.com). When viewing the posts, the title appears 2 times. In fact, it shows the name of the article plus the title that appears at the very beginning of each of my posts (which in fact are exactly the same). On the PC version, everything is OK. I have to say that I had to add this title at the beginning of the text of each post because the name of the post (box which appears under "Modify article") does not show anywhere when publishing on PCs. So, I added it at the beginning of the post and identified it as header1 so the font is bigger. Can you help me on this one ? Thanks, Anick
