IMDB seems to have mashed together my show and a different show I'm not affiliated with

Yesterday I logged in a season of a show that was already pre existing on IMDB. Today the episodes were approved and appeared on the site but they are mashed up with a show called Expedition: Robinson. The episode plots were all plots from their episodes, and their cast crew has been added on top of the cast and crew i logged to the episodes. Here is one of my episode pages: https://www.imdb.com/title/tt14444892/?ref_=nm_flmg_job_2_accord_2_cdt_epp_sm_1Here is their show page: https://www.imdb.com/title/tt0264245/?ref_=ttep_ov_iHow on earth did this happen and how do I begin to fix it?
