chart shows the additional year, but it doesn't appear in the left-hand filter

[sosiology]

After importing new data with an extra year, I edited the graph and selected the extra year manually. The chart shows the additional year, but it doesn't appear in the left-hand filter when it's not in edit mode. See https://int.visualize.admin.ch/en/v/52j3bDy8VD6e
