and if you want the backpack to appear on your back, you could just get some code to make it appear on your back if you have it in your inventory.

I thought the way the backpack looked was fine, I just thought that the mod for the pack it self seemed a little bit wrong (for lac of a better word) I just think the backpack as an item rather than an entity seems less likely to bug out.

I love your mod, but I don't really like the backpacks you used. If you want to use these (and can get permission), I recommend Backpacks Plus (https://modbay.org/mods/104-backpack-plus.html). It's not mine or anything, and it doesn't show on your back like your current one does, but I feel like it is less likely to bug out and is just better in my opinion.
