Hitbox size won't change despite changes to item width and height

[bubobucks]

I'm a new modder, so I apologize if this is a dumb question.

I have a few swords in my mod and they all work as expected, but my newest sword seems to have a hitbox of just one pixel. I messed with the width and height, but nothing changes. Am I doing anything wrong, or is there some obvious syntax error?

using Terraria;
using Terraria.ID;
using Terraria.ModLoader;

namespace MODNAME.Items.Weapons
{
    public class SWORDNAME : ModItem
    {
        public override void SetStaticDefaults()
        {
            DisplayName.SetDefault("SWORD NAME");
            Tooltip.SetDefault("The beginning of a journey");
        }

        public override void SetDefaults()
        {
            item.damage = 20;
            item.melee = true;
            item.useAnimation = 20;
            item.useStyle = 1;
            item.knockBack = 5;
            item.width = 900;
            item.height = 3600;
            item.maxStack = 1;
            item.value = 5000;
            item.rare = -12;
            item.UseSound = SoundID.Item1;
            item.autoReuse = true;
        }

        public override void AddRecipes()
        {
            ModRecipe recipe = new ModRecipe(mod);
            recipe.AddIngredient(ItemID.CopperShortsword);
            recipe.AddIngredient(ItemID.WoodenSword);
            recipe.AddTile(TileID.WorkBenches);
            recipe.SetResult(this);
            recipe.AddRecipe();
        }
    }
}

Thank you in advance for any help, I appreciate it!

Wait, quick edit.

It turns out the hitbox size is very long but only seems to go upward, and there is no horizontal range.
