Wrong RETURN direction in model after generating it from dynamic vdb

I had procedure parameter with direction RETURN(third parameter in vdb) and after generate model from dynamic vdb direction is OUT instead RETURN.
In dynamic vdb is mark for RETURN direction(RESULT) but it is propably wrong readed

CREATE FOREIGN PROCEDURE ff (IN newParameter_1 string(4000), INOUT newParameter_2 string(4000), OUT newParameter_3 string(4000) RESULT, OUT newParameter_4 string(4000))
