Trouble deleting countries from poster #8

Two times, I tried to delete the country Poland from this poster of Dutch children mini-series Carlo en Irene en de parel van de woestijn: https://www.imdb.com/title/tt0136635/mediaviewer/rm2934599424/ This mini-series never aired in Poland, nor was it promoted there. These are the contribution numbers: #250902-231944-028002 #250905-224252-215302 Can a staffer look into this and fix this please?
