Rowtype mismatch in DrillReduceAggregatesRule

It's work correct for example in case when there is only one aggregation:
select col1, stddev(col2) FROM(values ('UA', 3), ('USA', 2), ('UA', 3), ('USA', 5), ('USA', 1), ('UA', 9)) x(col1, col2) GROUP BY col1 LIMIT 6;
Or when it's after other aggregations:
select col1, SUM(col2), stddev(col2) FROM (values ('UA', 3), ('USA', 2), ('UA', 3), ('USA', 5), ('USA', 1), ('UA', 9)) x(col1, col2) GROUP BY col1 LIMIT 6;
But when we try to put it before an aggregation, like SUM:
select col1, stddev(col2), SUM(col2) FROM (values ('UA', 3), ('USA', 2), ('UA', 3), ('USA', 5), ('USA', 1), ('UA', 9)) x(col1, col2) GROUP BY col1 LIMIT 6;
It's failed with error:
SYSTEM ERROR: AssertionError: Type mismatch:
rowtype of new rel:
RecordType(CHAR(3) NOT NULL col1, BIGINT $f1, BIGINT $f2, BIGINT NOT NULL $f3, BIGINT $f4) NOT NULL
rowtype of set:
RecordType(CHAR(3) NOT NULL col1, BIGINT $f1, BIGINT $f2, BIGINT NOT NULL $f3, BIGINT NOT NULL $f4) NOT NULL
Same for stddev_samp
