Kicking out an adopted child says I have none, and they cannot move out themselves

Running:

LunaticLib 1.1.11
LunaticFamily 1.2.6
Purpur 1.21-2257-cb0f04b (MC: 1.21)

Description: After adopting a player, I cannot kick out and they cannot move out of the family. Trying to kick out says I have no child and them trying to move out generates an exception when confirming, pasted below. Listing the family successfully shows that we are in a family together.

Image of the issue:

/adopt propose <player> | interacted on accept
confirms adoption       | confirms adoption
/adopt kickout <player> | -
-                       | /adopt moveout
-                       | interacted on confirm (exception)
/family list            | /family list

Exception when moving out:

Command exception: /family adopt moveout confirm
