0. ALWAYS PROVIDE INFORMATION ABOUT MODLOADER (Fabric / Forge) AND MOD VERSION (For Example 1.19.2-8.2.10)
   0.16.5 FABRIC

1. Describe the bug
   Majority of the time the hose does not function. My keybind is "Z" I hold Z and scroll but the hose simply stutters but does not change into "Hose suck mode" etc, simply stays as "Hose". After dropping it, picking it up, taking backpack off and putting backpack back on, I can SOMETIMES get the hose to then function normally for a very short window.

Tools function correctly with the keybind, removing tools does not fix the hose issue.

2. Write steps to reproduce the bug
   Equip backpack
   Check to make sure you have no conflicting keybinds
   Hold hose in hand with no offhand
   Hold keybind for "Swap Tool/Change Hose Mode"
   Scroll mousewheel
   Hose simply stutters as if something is changing but hose remains as "Hose"

3. What is expected behaviour
   Hose will change from "Hose" into "Hose suck mode" "Hose drink mode" "Hose spill mode" etc while holding keybind and scrolling.

Do you play on modpack from curseforge/modrinth so I can download it and make tests?
