Issue of Credit

Dear Admin, I am one of the directors of photography for newly released 2-episode documentary series "Kursk: 10 Days That Shaped Putin" https://www.imdb.com/title/tt35931093/ I edited the page and add my name to the credit under camera department in 2 episodes. After it was approved, I checked my profile page: https://www.imdb.com/name/nm15736257/?ref_=nv_sr_srsg_0_tt_0_nm_2_in_0_q_patrick%2520chengzhi%2520wang But I found my credit is only written in the 1st episode. Could you help me fix the issues?
