"Welcome" text is shown and cannot be removed, even with non-empty database

[Google Code Exporter]

What steps will reproduce the problem?
1. disable all lessons except one (not necessary, but helpful)
2. select method for new lessons: In Order
3. on typer tab, complete the remaining lesson; You will now see the 'welcome 
text'

What is the expected output? What do you see instead?
I do not expect to see the welcome text unless my database is empty, as it 
states in the welcome text itself.
The welcome text cannot be seen and thus removed from the sources tab, which 
might otherwise be a workaround.
Pressing Esc when in order mode does not skip the lesson.

What version of the product are you using? On what operating system?
Amphetype-0.16-win32.exe
Windows 8.1 64
