Fix simple code on my product page on my website in shopify.

Someone form one of the apps I am using messed up my product page. On my product page my Add to Cart and Buy it Now buttons are currently half size - they must be restored as full size buttons as before. And also I had a part promoting a financial payment, and also timer and and a message - these were moved under my description, but should be moved back under the title. I will send you screenshots. And lastly I need to move the position of the star reviews from judge.me under the title as well. I need all this fixed asap. Thanks
