Excluding column on chart in ggplot2

I would like to exclude one column from my chart. In csv I use as my data there is a lot of empty cells and thus there is nameless column in my chart that is at the same highest of them all. In my opinion it looks a bit stupid so I would like to get rid of it.

Here is my chart code:

ggplot(df, aes(Coverage, fill=(Coverage)))+
  geom_bar(color="black",fill="brown3")+
  theme(text = element_text(size=15),axis.text.x = element_text(angle=90, hjust=1))+
  labs(title = "Diagram przedstawiajacy w ktorym miesiacu w kolejnych latach najwieksza liczba dziennikarzy poniosla smierc", x="Panstwo", y="Rok")

And here is how the chart looks like. First column is the one counting amount of empty cells.

thank you very much for all the help!
