Binaries/UE4Editor.modules values are being changed when I run my project

When I try to run my project. I receive a pop up saying : “the modules are built incorrectly or with a different engine unreal - UE4Editor.modules”. When I looked into it I have found that whenever I run the project a line in the file is being changed from “example”: “UE4Editor-Example.dll” to “example”: “UE4Editor-Example-XXXX.dll” where XXXX is some random integer. I can “fix” the problem by editing it back to the original, but I don’t want to have to do that every time I reopen the project and I would also like to know why this happens. I am new to Unreal so any information is appreciated!
