I'm dealing with this right now in 2.6.2. I closed the rematch window, edits have all been saved. I just removed all the pertinent layers and saved ArcPro and the leftover rematch symbols are still there. Irritating. It's happened on every layer I've geocoded this month. It went away after I reopened ArcPro, but still, irritating. Screenshot below. Where would I find the rematch window to reopen and try to get rid of these?
Edit:
I RC my imported CSV table & clicked "geocode table." Used the ArcGIS World Geocoding Service.
This persists among multiple outputs from tools. My workflow takes the output of the geocode and does a few spatial joins, projects, and exports from a gdb to shapefile. I turn off previous layers and it still persists, but I've not removed them individually to test.
