To get around this bug for now just make sure to open a KI1 core before opening a KI2 or KI3 core until the dev fixes this.
To the dev, below is the fix and replication instructions that I found for this bug
Replicate this by placing and opening the ki2 core before placing a ki1 core.
Easy fix is changing line 312 and 402 in /scripts/gui.lua to
minimum_value = 0,
Could also fix it by making sure the max is always greater than 1 by using math.max on line 313 but that seems silly in comparison to just keeping the min value always at 0... then again lua tends to start at 1 instead of 0 unlike other programming languages so using math.max(#storage.ki.channel + 1, 2), for lines 164, 313, 403 may be a better option and have the min always set to 1.
Have not done any in depth looking at the coding of the beacons to understand what would be the best option.
