For some funds that have just been launched, Fund Managers will agree to rebate expenses in order to keep costs down to an acceptably low level, so as not to be a drag on returns which are used in marketing materials.
Once sufficient scale is achieved, normal expense ratios will return. I do not know enough about the Funds you have mentioned, but the above could be one reason.
International contains a lot of good and a lot of crap. With so much to choose from you would expect a good manager to be able to outperform.
The problem is there is so much data to research because the companies operate everywhere, that you have to find a manager of sufficient scale who will know everything.
Scale tends to lead to big funds, which from a stock selection point of view, tend to gravitate straight back to indexes, and are not as nimble as smaller funds (which have resulting higher volatility and deviations from the index.
I am rambling now without a coherent point of view, but I hope you get the gist of it.
