When grouped layers are deselected and reselected in the interactive legend, groupings with more than 1 layer attribute do not reappear. This can be seen in the below images where the first image shows the initial map view and the second image shows the map view after all 4 layer groups (Temporary, Still, Flowing, and Treated) have been deselected and reselected. For reference, Temporary is the only layer group with only 1 attribute source, all other layer groups are groupings of MULTIPLE attribute sources.
In addition, for other layers with groupings that include multiple attribute sources, the interactive legend previews a new layer group for each attribute source, just all with the same name:
Does anyone know why the interactive legend functions this way? Any suggestions on how to solve it (other than uploading problem layers with a new attribute field that separates each layer group through a single attribute source)?
