You need to take the talent twice to get access to the 6th-level feats.
Here's the talent in question:
Ranger Combat Style talent wrote:
Benefit: The slayer selects a ranger combat style (such as archery or two-weapon combat) and gains a combat feat from the first feat list of that style. He can choose feats from his selected combat style, even if he does not have the normal prerequisites. At 6th level, he may select this talent again and add the 6th-level ranger combat feats from his chosen style to the list. At 10th level, he may select this talent again and add the 10th-level ranger combat feats from his chosen style to the list.
The basic benefit of the talent is that you get to pick a combat feat from the first feat list of the chosen style without having to meet its prerequisites. At 6th and 10th levels, it is explicitly noted that you must be taking the talent again in order to receive the more advanced benefits.
