Bug: an existing heatmap is not displayed in popup designer
Error happens when
1) I have a popup with a stat with an active Heatmap
2) I delete or disable the Note that produced the heatmap
I now can't see the Note in the Heatmap selector dropdown menu, it appears as if there is none.
The orange heatmap-overlay is still there though and opens up empty in the popup.
There is no way to remove this Heatmap without going to the .pop manually.
