Blooper with SPOILER alert is NOT shown on website, but it's ok on the App

Hi, Checking blooper page on the website for a FUBAR episode (https://www.imdb.com/title/tt18500790/goofs/?ref_=tttrv_sa_1) only TWO goofs are shown. But on the App I see three.  The "missing" one has a "SPOILER" alert, maybe it's related to this?
