I was using Grid mode to space out some lamps in the ground using replace and spacing them out. After I was done I tried to reset the grid down to try a different spacing but was unable to lower any of the values in the "Grid" field.

I am having this issue on version 2.6.8 on Fabric. I am playing on a server hosted on the computer I'm playing on. I have relogged, restarted server, removed the wand from my inventory, tried placing with the crazy long grid to see if that would clear the settings but nothing does. No matter what I press Shift or CTRL to go up it only goes up by one and no mater what I press the numbers will not go down. Any help with resetting the config would be appreciated.

Found a solution for now to set it back down. Using the keybinds "GridM/Mult Decrease" and "GridN Decrease" works to set it back down but config menu still not updating wand

I have the same problem here, I can't back down in grid mode.
