There is a very good reason why there isn't a line there. The table structure of that section is fairly complicated, and it would be a big pita to correctly retain the table structure if you remove the way Infopop has already done it.
I can probably figure it out if I try really hard, but you're on 6.05, which makes a problem. Anything I figure out will have to be on the latest 6.1, because I don't have any 6.0x files anymore. So even if I post code to change it, it most likely won't work. If you feel like upgrading your board to the latest 6.1, I can work on figuring it out for you - otherwise you'll have to wait till someone who still has 6.05 figures it out.
