Package shipping 4.15 errors in AnimSequenceBase.h and ArrowComponent.h

Good morning everyone. Recently I tried to pack a shipping build from a UE4 project, but the errors in the image below popped up on the process. They seem to be related with the external dependences “AnimSequenceBase.h” and “ArrowComponent.h”, classes owned by the engine that cannot be modified in any sense.

I have a mate with the same version of the engine and it compiles and packages perfectly on her machine. Our version is a source built 4.15.1 of the Engine.

Any ideas why this is popping up while building a shipping package in my terminal?
