Cannot use the projectile feature (and many other features)

I am completely new to MCreator, and I was hoping to use it to make bedrock mods to use with my friends on Xbox, seeing as their mods are crippling limited to Mojang's marketplace restrictions. I was hoping to make a mod that uses tools that fire projectiles, but when I went to the Advanced Properties on the item I was making, it was grayed out with text that reads "! Not Supported", as are all the other Properties in the Advanced Properties tab, and so many more outside of it. Is this because my PC runs off Windows 10 and not 11? Or is it something else. I am running off of MCreator 1.21.1 so I don't think the issue is the version I am running off of.
