Second row may or may not show up I enabled the second row. Sometimes it's there  sometimes it's gone. I use around 10 apps daily so a second row is really needed so that I don't have 10 icons squeezed in one row. I could have tone it down to show 5 apps per row but without the second row to show the remaining 5 apps it would defeat the purpose of wanting to have the most convenient access to my 10 frequently used apps. Please look into this bug (if it's actually a bug) or tell me if I configured it incorrectly.
