Unweighted/Weighted GPA

I am an international student and since the definitions for unweighted and weighted GPAs in US high schools don’t match with the GPA definition in my country, I put my GPA and rank as unweighted but I learnt that my counselor put my GPA and rank as weighted.(Our GPA is a weighted arithmetic mean of our scores in all courses rather than the arithmetic mean of course scores in which max score of harder courses are higher than easier courses like when calculating weighted GPA in US)Will this pose a problem? Should I email admission offices to say that it is actually weighted?

Also, I think my counselor will explain how my GPA is calculated in midyear report but would the discrepancy between what I classified my GPA and rank as and what my counselor classified my GPA and rank as hurt me?

No problem. The schools will use your GC’s info.
