MySQL DataType - BIT size and default not captured on Snapshot

Create table like so:

CREATE TABLE TESTBIT(
BIT_NULL BIT(6) NULL,
BIT_NOTNULL BIT(6) NOT NULL,
BIT_DEFAULT BIT(6) DEFAULT '1',
BIT_PK BIT(6) NOT NULL,
BIT_UNIQUE BIT(6) NOT NULL,
CONSTRAINT PK_BIT PRIMARY KEY (BIT_PK),
CONSTRAINT UN_BIT UNIQUE (BIT_UNIQUE)
);

Note the sizing of BIT(6). Take snapshot and note the size is BIT(1)
