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

Forge 1.20.1

1. Describe the bug

Hello, I hope you have a nice day.
First, thank you for all your effort and dedication to the mod. It's one I've always used since I started playing Minecraft.
I play with Forge version 1.20.1. I noticed something that seemed very unusual, but I'm not sure if it's just with this version or with the modloader itself.
I can't equip the backpack. I've seen videos, and I think the problem is that I can't see the icon to equip it.
I did what I found on this forum: https://www.reddit.com/r/Minecraft/comments/1fng3rr/travelers_backpack_icon_disappeared/

I checked the value:
"Whether the backpack icon should be visible in player's inventory"
and it was set to true.

I would be very grateful if you could help me.

2. Write steps to reproduce the bug

I don't know

3. What is expected behaviour

be able to equip the backpack on your back

4. Screenshots (If applicable)

If the button is not visible, then you have to equip backpack by equipping it in the "Back" slot of your player, it's automatic integration. You can disable it via travelers backpack config though
