I am having a problem not being able to select layers using the Select Widget on Web AppBuilder. The Select Widget only shows one layer selected (even though multiple layers are selected) and never produces the requested multi-layer results.
The image below demonstrates the problem I have: it should select the Forest Stand layer (red circle) in addition to the Birds layer. (The Select widget has a simple configuration, so I don't know how to fix this problem). Is this a bug in the widget or there are some problems in the way I published the layer? I would very much appreciate if you could assist me in this regard.
