"I also noticed that whenever I generate a report, the lower-left corner icon for viewing the data table is missing."
This is by purpose as you are working in the project. The data table is listed in the window list on the left within the project so you can navigate easily to it whenever it is needed. If you miss this window list you have to go to the menu item "Project" and select "Show Window List" to show this window again within the project.
Hope this helps.
