why are there (slightly) different statistics among different websites for the same fund?

I generally assume the statistics (especially expenses-related statistics) for any given fund should be the same across different websites as they collect the information from the same resource/origin.
But I came across the following example and am seeking some clarity and the best practice to find the accurate statistics. Thanks.
