MySQL 6.0-38, testd database, created a table

CREATE TABLE `testinsert` (
    `col1`    varchar(25) NULL
    )
INSERT_METHOD = FIRST

When I go ALTER for this table, Storage Options are all blank

If I script Create Full this table, it doesn't give me the insert method.

I also have testdba table where all Storage Options are defined. Insert Method is DEFAULT.

Verify.
