Cant install this version

[GhostAdminOne]

Tried pretty much everything to get this addon to load, but it just blows up left and right.
`3x ...ceSushi-3.2-1/classes/buttons/ExpandHeader.lua:1: attempt to index field 'Clickable' (a nil value)
[string "@Sushi-3.2-1/classes/buttons/ExpandHeader.lua"]:1: in main chunk

Locals:
(*temporary) = nil
(*temporary) = nil
(*temporary) = "Sushi-3.2"
(*temporary) = nil
(*temporary) =

{
Base = {
}
Meta = {
}
}
(*temporary) = 1
(*temporary) = "attempt to index field 'Clickable' (a nil value)"`

Tons more like this.
