Thank you for your help. I've been away from the office,  just getting
back to this. Here's the json output for a polygon that generates the
same error reported before:

blandings:PERM> v.what -j map=Obs_20170329 at PERMANENT
coordinates=1548324.30568,12154706.4547
{"Coordinates": {"East": "1548324.30568", "North": "12154706.4547"},
"Maps":
[{"Map": "Obs_20170329",
"Mapset": "PERMANENT",
"Type": "Area",
"Area_height": 0.000000,
"Sq_Meters": 3086589.260,
"Hectares": 308.659,
"Acres": 762.713,
"Sq_Miles": 1.1917,
"Categories": [
{"Layer": 1, "Category": 2744},
{"Layer": 1, "Category": 13236},
{"Layer": 2, "Category": 2}]}]}

I don't understand that, but is it suspicious to see two different
categories in the same layer?

Best,

Tyler
