WP_Query not ordering correctly

I have two custom user meta fields created with ACF. One is quantidade_corretas_dia_4 (Numeric, integer) and another tempo_dia_4 (Numeric, decimal). I am using WP_User_Query to get users ordered by both this values like this:

However, i cannot understand why my results are being ordered by quantidade_corretas_dia_4 but not by tempo_dia_4. Here is an example of what i get:

enter image description here

I expected user with ID 44 to be placed before user with ID 65, since they have same quantidade_corretas_dia_4 but tempo_dia_4 is different (lesser in ID 44 than ID 65).

What am i doing wrong in this query?

Thanks.
