seaborn pairplot doesn't show all labels

[winderia0236]

I have a question for seaborn pairplot, i used the code like sns.pairplot(df, hue="label") to draw a pairplot, but my labels contains about 10 labels (from 1 to 10), but the labels only shows part of them, for example, only show 2,4,6,8,9,10, how can I solve this problem?
