My TickingArea size does not match with the size I put on the commands

I'm making a Skywars map that requires some areas always active, so I have to use "tickingarea" command. I put the following command: /tickingarea add 16 5 18 -28 100 -32 Lobby, but when I click Enter to execute the command, the coordinates of the Tickingarea that creates doesn’t match with the coordinates: when I put from 16 5 18 to -28 100 -32, it creates from -32 0 -32 to 31 0 31, area that doesn’t cover a single block of my area. I think it’s a bug because the feedback didn’t advise me of a syntax error or something like that. Here is the video:
