The deformers dissapear when i package the game

Hello there! I have ran into a problem with the plugin i just got.

So in the unreal engine editor everyhting works fine i have 0 issues my deformers and collisions are placed exactly where i need as you can see in the first screen shot.

However when i try to package the project, some things seem to be stuck (front bumper and 1st person camera) at the spawn point. Also when i toggle on the colliders, the deformers disappear and the collider from the car gets stuck at the spawn point. Also when i try to crash into walls my car just goes through. Te third screen shot is the 1st person camera

Also I need to tell you I am a beginer developer in unreal engine.

If anyone can help me I will appreciate it alot!
