Help! Calls to a PROCEDURE RETURN with inputs does not have input connectors

Dear admin and community, have you encountered this?

PROCEDURE DO with input works well, but in our project, using:

Windows XP,7, or 8

Chrome (latest version),

any call to a PROCEDURE RETURN with inputs

doesn't have the input connector.

Please help. We need it in our class project :(

that's a bug

use the procedure from the procedure drawer and you get the input parameter
