When I wanted to trade with the cartographer to get a map, I found that if I click on the list on the left side to fill the emeralds and compasses into the trading grid, I cannot get a map. But if we manually put these items into the grid, I can get the map as usuall. The situation only happens on trading maps with the Cartographer.
