While importing data in SQL Developer using Data Import Wizard, the following is observed:
1.Specify 「CHAR」 for data type of column1 and change its size/ precision from  to 「8」.
2. Navigate to another column in the Wizard.
3. Navigate back to column as in step 1 ( which was previously modified).
4. Select column1 again, the size/precision is now changed from 「8」 to 「26」.
Effectively modified changes are lost.
