History Graph data not staying hidden when label selected

With a history card one can hide a set of data by tapping the label of the data. The label will get a strike-through and the data will be gone. As of recently when I tap on the label the data will go away, but then after some seemingly random amount of time the data will come back (this is new and undesirable, I believe likely a bug). The strike-through on the label will remain even when the data comes back without tapping on the label.

This issue occurs both in my web browser and on the companion app on Android.
