Error on /spreadplayers ~ ~ 0 1 false @p[r=3]

I'm running a test world, single-player. The buttons appear to work correctly and everything appears to work correctly until I attempt to leave. The box you stand on at the top does not work. I tested "/gamemode 3" to verify I have cheats enabled, and I made a "say "hello" " command block to verify that part was working.

The box at top will do "say "hello" " when the command is replaced.

/spreadplayers ~ ~ 0 1 false @p[r=3] when I type it in the text box returns the following error:

Could not spread 1 player(s) around --163.0,281.0 (too many players for space - try using spread of at most 340282346638528860000000000000000000000.00)

I can easily enough make this a /tp @p up to the surface, but this could become an issue for others. Does the command need tweaking?

Note: Quote of the Install Video, "If you encounter bugs, feel something is underpowered or overpowered, please let me know on my sub-redit at ...."

Not supposed to post bug report here though according to the subredit rules. I did post this on the YouTube, and I'll hop into Discord as well. Just to say, I'm trying to follow the rules as I understand them while making sure the bug report gets noticed on this release. :)
