Anyone else seeing magenta ("pink") ghost captions on the BBC's Olympics 2018 coverage...? It's not there all the time and only seems to affect certain shots in certain events, (mostly skiing and snowboarding,) but I see it fading in and out of vision and the bottom left and bottom center of picture. It looks a BBC logo bottom left and possible some ident text bottom center (it's unreadable.) Anyone else, or is it just me...? I should probably add, watching on FreeSat.
