The champions summon and summonpos commands do not work in a Command Block

[Toastr125]

Versions (Be specific, do not write "latest"):

• Champions: 2.1.6.3
• Forge: 40.2.0

Observed Behavior:

No champion is summoned. Entering the same commands in chat works just fine, it is only when a Command Block is used that they do not work. Additionally, the Command Block's "previous output" box is empty.

Expected Behavior:

Triggering the Command Block would summon a champion mob. I understand the champions egg command not working since there is no target player to give the egg to, but I would expect champions summon and summonpos to work fine since there is not a target player involved. (If a player is needed anyway, perhaps a player selection field could be added to the command syntax?)

Steps to Reproduce:

1. Place a Command Block
2. Enter a champions summon or summonpos command (for example, I tried "champions summon minecraft:zombie 1" and "champions summonpos -3 73 -8 minecraft:zombie 1", with -3 73 -8 just being the coords of the Command Block)
3. Trigger the Command Block
