Inserting a Row or Column into a Table or a Task into a Timeline created using a Style will insert without the Style. In other words, the newly inserted Row, Column or Task will look different than the original rows, columns or tasks because it was inserted without a Style.
Solution:
1. Click on any cell in the Table so that it is selected.
2. Choose Model Styles... from the Table menu.
3. Choose the Style that you want applied to the entire Table.
4. Click the Apply button and the click Done.
