The version currently hosted on MEGA doesn't have the fix to the Inventory Editor addon.Dude by the first time i downloaded cheat mode it was from that post.
There is a secondary link for that addon that fixes the group error in versions after 0.8.8.0.
Once the mod gets to v1.0 proper the version on MEGA will match the version on github.
The MCM branch on github is the fixed MEGA version (and is All-In-One) and only that branch should be downloaded via the Code button (MCM branch must be selected) Though that version is no longer supported.
