Okay, so returning to my original post, this was the problem: There was no description for the photo that needed to be added. But then… if there’s a description, it is displayed on the slider bottom as text overlay, witch I DON’T want. So I solved this by cutting the desctiption and putting it in the SEO description (in the SEO tab). So yeah, this seems to be a MetaSlider bug, but it’s nice to have a workaround. Thanks guys!!!
