I made a test map with ArcMap 10.8.2 I added two layers. When I select one of the layers in the Table of Contents, right-click and Zoom to Layer, that layer appears. When I select the other layer, the previous layer disappears and the newly selected layer appears. Any idea why I cannot see both layers at the same time?
