qgis - XY points not showing up on map after adding new rows to attribute table

In QGIS, I added two new rows, but the points are not showing up on my map even though I inputted their LAT and LONG's. The rest of the rows LAT/LONGs show up on the map (they were part of the original table I added). I already went into field calculator and specified that LAT was $y and LONG was$x...but that didn't solve the problem. How do I get the points to show up?
