View does not show column type

Question

I have two views containing a column, which is defined exactly in the same way. One view shows the column type as VARCHAR2 (200 CHAR) and the other does not show anything as the type.
Here is the screen shot:

First question: why is there a difference?
Second question: why is the type VARCHAR2 although the modeler does not know VARCHAR2 but only VARCHAR as a column type?
Here are the definitions of the views:
This is "user_status":
WITH user_status_data AS
(SELECT work_user_status_data.person_id,
MAX(work_user_status_data.startdate) AS startdate
FROM work_user_status_data
GROUP BY work_user_status_data.person_id
SELECT person.id AS tmdid,
person_a.lastname,
person_a.firstname,
person_a.email AS emailaddress,
person_a.address
|| ', '
|| person_a.zipcode
|| ' '
|| person_a.city
|| ' '
|| person_a.country AS postaladdress,
person_a.phone,
person_a.mobile,
person_a.company AS organization,
person_a.orgunit_abbr AS orgunit,
work_user_status_data.pwdresetflag,
work_user_status_data.lockaccount,
work_user_status_data.primarypwd,
work_user_status_data.expdate,
work_user_status_data.iamtid,
work_user_status_data.startdate,
work_user_status_data.stopdate,
'IN PROGRESS' AS status
FROM person_a
INNER JOIN ts
ON ts.id = person_a.ts_id
INNER JOIN person
ON person.id = person_a.person_id
INNER JOIN user_status_data
ON person.id = user_status_data.person_id
INNER JOIN work_user_status_data
ON user_status_data.person_id = work_user_status_data.person_id
AND user_status_data.startdate = work_user_status_data.startdate
WHERE ts."until" IS NULL
And this is "work_user_status":
SELECT person.id AS tmdid,
person_a.lastname,
person_a.firstname,
person_a.email AS emailaddress,
person_a.address
|| ', '
|| person_a.zipcode
|| ' '
|| person_a.city
|| ' '
|| person_a.country AS postaladdress,
person_a.phone,
person_a.mobile,
person_a.company AS organization,
person_a.orgunit_abbr AS orgunit,
work_user_status_data.pwdresetflag,
work_user_status_data.lockaccount,
work_user_status_data.primarypwd,
work_user_status_data.expdate,
work_user_status_data.iamtid,
work_user_status_data.startdate,
work_user_status_data.stopdate,
work_user_status_data.action,
work_user_status_data.progress
FROM person
INNER JOIN person_a
ON person.id = person_a.person_id
INNER JOIN work_user_status_data
ON person.id = work_user_status_data.person_id
INNER JOIN ts
ON ts.id = person_a.ts_id
WHERE ts."until" IS NULL

Answer 1

I just found out that the engineered version (10g) is also quite strange:

It shows the values in the columns for the types.
This looks very buggy.
Is it not recommended to create views with the data modeler?
