Why the table has a configuration of rounding and the graphs another?

See this example that uses the same data source and filters:

Table total number: R$2.382.224

Same filters, but has a graph: R$2.382.218

When I change decimal config to 2 decimals in the column from data source table, they match! But just when I do this! 

Result (right result):

See that the rounding from the graphs are the right one, cause R$2.382.217,61 is indeed R$2.382.218.

Should this happen? I really don't want to show decimal cause they are bigger and always overlap other numbers in graphs. And table and graphs should be equal, has the data is equal! Conclusion: the table number rounding is wrong or I'm missing something. Please, help me solve this or, if this shouldn't happen, correct this Zoho Corp.
