Problem with blueprint AGAIN, locked out of projectile blueprint

This time I was editing a Projectile Mesh for my gun, the physics for some reason wasn’t working, the bullet would just fall out of the gun and
float down to the ground even when I had cranked up the velocity so something was wrong, until I finally turned the physics off the Collision box. Now the physics for the projectile started to work under simulate mode in the projectile’s viewport but in the game viewport world nothing was spawning from the gun at all, the mesh projectile wasn’t spawning in the real world and didn’t know why. Then when I went back to edit the bullet Blueprint, only to find that the whole thing has now been all greyed out under components, and i can no longer edit the BP components section anymore, my projectile blueprint has now been locked down by the engine as read only.

Although its not a solution
keep Duplicating your Important BP’s if you make big changes Just in case you mess on up

I just hit save all, and closed a ennumeration file I had open for editing, now that Bullet bp has become avaliable for editing again, but
I need some help in getting the projectile of this gun system to spawn in the real world. I’ve got the 3d camera modes now working but not the spawn projectile for the firing. I just want the projectile to spawn out of the weapon each time I fire but for some reason when I play game in PIE mode the projectile is not showing up in the game world.
when I fire I see nothing happening on the screen.

But the damage system of the gun still works to kill enemies and increase exp points.

Code

Does anyone in here know why the Gun Projectile won’t show up?
