RERGX 5year return question

I have RERGX (Dodge & Cox American Funds EUPAC Fund Class R-6) offered in my company 403b and was wondering if I am missing something or just confused about the 5year return. Morningstar has a return of 34.77 while google has a return of -13.39. These are wildly different returns and I wasn't sure what to make of it. Also while on Morningstar I noticed next to the time period you can also select frequency from daily, weekly, and monthly and each one has a different rate of return, which confuses me. Lastly why did they name it American Funds when all of its holdings are international? Disclaimer: I am not investing in this fund based on past performance. I am just trying to learn and understand the difference in past returns. If i happen to be in the wrong community could some please direct me to a community better suited for my question. I had problems linking photos on numerous financial communties. Thank you for any and all help.
