Array out of bound when reaching the end of the toolbelt. (7DTD-fpsHUD Mod) (UI modders help needed!)

[BoQsc]

I downloaded one of the UI mod  7DTD-fpsHUD Mod .

I keep on wondering why this is happening in the 7DTD-fpsHUD Mod 

Once I reach the end of the Toolbelt (8th slot) using mouse scroll wheel, this error pops up and I'm not sure what to do to fix it.

Anyone have this experience in 7DTD UI modding?

IndexOutOfRangeException: Index was outside the bounds of the array

A19 now has 10 slot toolbars in base game. Chances are that UI mod hasn't been updated to be compatible with A19 seeing as it was updated last in September of 2020.
