I am having a problem with this addon, here's the error details

user:/AddOns/InventoryGridView/lib/LibAddonMenu-2.0/LibAddonMenu-2.0.lua:147: attempt to index a nil value
stack traceback:
user:/AddOns/InventoryGridView/lib/LibAddonMenu-2.0/LibAddonMenu-2.0.lua:147: in function 'RefreshReloadUIButton'
user:/AddOns/InventoryGridView/lib/LibAddonMenu-2.0/LibAddonMenu-2.0.lua:157: in function 'RequestRefreshIfNeeded'
user:/AddOns/InventoryGridView/lib/LibAddonMenu-2.0/controls/checkbox.lua:65: in function 'UpdateValue'

I dunno how to fix it i've tried to delete and reinstall but it doesn't work.

Thank you!
