Your first Netmonitor screenshot does indeed show an LTE connection, but it is not the same base station mapped in the other screenshot. Between those snapshots, your connection must have changed. Or something else is awry.
when i was in the area i was connecting to three towers one not in pic just north of my location. i have a screen shot of the tower but im getting file is too large to post here.
