Command Bug

Hello, I am the owner of a professional building realm and we discovered a slight bug that makes building slower. If we needed to edit a command (such as using /fill) the text will disappear if we already pressed enter to save our previous inputted information. For example, if we entered /fill and our x1,y1,z1 , pressed enter to save our information then head to the second block location, clicking on our previous command causes the box to clear and not allowing us to actually edit the command. We would have to start from the beginning with entering the /fill command. This bug is for bedrock in general. It has been reported to me from our windows, Xbox and ps5 players.
