Update within group?

After clicking the update button on the "CursorCastbar" aura, I get this Lua error.

I'm pretty sure the whole group should update, not just those two children.

1x WeakAuras\Transmission.lua:1207: attempt to get length of field 'controlledChildren' (a nil value)

What happen here, is that Group "CursorCastbarGrp", "CursorCastTime" and "CursorCastTime" have their version field set to 7 which is the last version found by Companion.
"CursorCastbar" and "CursorGCD" have (for a reason i ignore) their version field set to 2, while their url shows version 7.
So Companion link the updated version only to those 2, and not the group.

The migration from 9 to 10 update version field only if version == nil and it seems to be a mistake.
