Cruising along in lightroom, edits completed, File>export with preset>choose preset > export. Export completes, jpeg is there in folder (same folder) I want; BUT: my filter bar which had been set to >= 2 stars now changes to "no filters'. I have to click on filter bar to reactivate filter. Not a catostrophy, but an inconvenience. Working on a PC system, using cc photographers package - all updated. No other problems noted. Bug? "By design"? Some errant setting wrong by user error?
