Question about new hand pump

I ordered the gx hand pump off Amazon. Up on receiving the pump I notice it was covered in oil, clean all that off and notice it was coming from a hole in the psi gauge which was full of it. It all leaked out threw that hole. Tested it with the hose capped and it pumps to 200bar no problem. I watched an unboxing on YouTube and it looks like the psi gauge is suppose to be full of oil, but his didn’t leak out. Do I have a problem? Really don’t want to go threw the hassle of returning it.
