I've managed to zip the angelo meadows and angelo_road_trails spatial data files and, once the mime type is set to application/zip and the extractor re-run, they appear in the list on the geo-webapp interface. However, no features/data appear from them on the maps. Note that the angelo meadows data came from a zip file that I deleted in the sead acr. The roads_trails set is a recent add and is still there.
