No solution to double site title

My website http://www.ozgurniflioglu.com.tr ; which is run by Pure & Simple theme. My problem is it has two titles while sharing in facebook, and searched in google. My web site title is: Uzm. Dr. Özgür Niflio?lu | ?ç Hastal?klar? Uzman? but when i share in facebook i see double page title like Uzm. Dr. Özgür Niflio?lu | ?ç Hastal?klar? Uzman?Uzm. Dr. Özgür Niflio?lu | ?ç Hastal?klar? Uzman?; i have tried every option; like changing themes header.php; installing smart crawl etc. Besides that i don't use yoast seo plugin if you ask i will say in advance. I am sending screenshot of the facebook share.
