I'm fairly new to ArcGIS, but I've been working on it long enough to get very frustrated with my inability to select points in my layer.
I'm working in ArcMap 10.5
My problem is this: I've got 5 layers, either points or lines. All of them are listed under Table of Contents as selectable. 4 of the layers can be selected without a problem. However, the 5th layer cannot. If I right click that layer and hover over selection, none of the options are available. Also, if I attempt to 'Set Selectable Layers' from the customize toolbar, the 4 working layers are listed (and checked), but the 5th layer is not listed.
Any tips or other things to look for?
