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

Minecraft 1.21.1 fabric loader 0.16.10-1.21, Traveler's Backpack v10.1.15

1. Describe the bug
   The slots for the upgrades such as pickup and void are staying at 9, even though I increased the number to 18 in the mod settings. It just shows a texture, and a messed up one at that.

2. Write steps to reproduce the bug

Go into mod menu or the config file > Traveler's Backpack settings > Backpack Upgrades Settings > Pickup or Void Upgrade Settings > Raise it above 9. Now view the item slots for either of these upgrades

3. What is expected behaviour

There should be more than 9 usable slots, and a texture that makes sense.

4. Screenshots (If applicable)

Currently, it's capped at 9 slots, but I will mark this issue as enhancement and work on it soon
