Source control issues (Git)

Hello, I am pretty new to the Unreal Engine, but a friend and I have been working on a project together. For some reason, components attached to objects in our level do not transfer along with source control. Currently I am ignoring a few directories with stuff that Unreal and VS generate as recommended to me. Does anyone have any advice? Currently my gitignore looks like this:

##########################

Unreal Generated Files

##########################
Intermediate/
Binaries/
Build/
Saved/
DerivedDataCache/
Content/StarterContent/

###########################

Visual Studio Files

###########################
*.VC.db
*.suo
*.VC.opendb
*.sln

Any help is greatly appreciated! So thanks in advance.
