can't trade with villagers

The version of Minecraft is what the game is calling the latest release version 1.14.3. When playing Minecraft realms villagers will become unable to trade. When attempting to trade the villagers trade GUI window will momentarily show up then disappear. This occurred first with a villager that we had not traded with and then again with a villager we leveled up to an apprentice. This bug affects all players. Please fix this bug, Thank you.
