The problem is not with the query, the problem is with the field names. A query that searches repeaters and also matches rows on a repeater is impossible.
The meta names of repeaters are "{$repeater_name}_{$row_index}_{$sub_field_name}"
The documentation and function/filter you are using causes the query to ignore the {$row_index} so if any row has a matching value in the first sub field and any other row has a matching value in the other sub field then the post will match.
The only work around that I have ever found is to use an acf/save_post action to get the values of the repeater and I store a multidimensional array in a WP option. Each element of the array is associated with the post. then I search the multidimensional array to locate the post IDs that need to be retrieved.
$option = array(
// nested array for each post
$post_id => array(
// nested array of values for each row of the repeater
array(
// field name => value pairs for each row
'field_name_1' => 'value_1',
'field_name_2' => 'value_2'
)
)
)
