I added more lines to my little test and I see that the right tab works, but not on the first line. On the first line, things are odd (to say the least). I'm including the image as an attachment (Not sure how to embed it)
The text used in this test is the following
Banane 3, 4
Plantain 3
Beef 8
Chicken 9,10
PS: I'm using 1.4.6
