Bah, teach me to read fast.
Ok:
Long bow: No strength penalty to attack but there IS a strength penalty to damage.
Composite Long Bow: -2 penalty to attack if you do not have a high enough strength (10 for a minimum Composite Long Bow). Apply strength penalty to damage.

+6 is correct.
Are you using a composite longbow or just a longbow?
Composite longbow:
Description: You need at least two hands to use a bow, regardless of its size. You can use a composite longbow while mounted. All composite bows are made with a particular strength rating (that is, each requires a minimum Strength modifier to use with proficiency). If your Strength bonus is less than the strength rating of the composite bow, you can't effectively use it, so you take a –2 penalty on attacks with it. The default composite longbow requires a Strength modifier of +0 or higher to use with proficiency. A composite longbow can be made with a high strength rating to take advantage of an above-average Strength score; this feature allows you to add your Strength bonus to damage, up to the maximum bonus indicated for the bow. Each point of Strength bonus granted by the bow adds 100 gp to its cost. If you have a penalty for low Strength, apply it to damage rolls when you use a composite longbow.
If you are using just a longbow then:
Description: You need two hands to use a bow, regardless of its size. A longbow is too unwieldy to use while you are mounted. If you have a penalty for low Strength, apply it to damage rolls when you use a longbow. If you have a Strength bonus, you can apply it to damage rolls when you use a composite longbow (see below), but not when you use a regular longbow.
Hope that helps.
That's still the rule for longbows and bucklers -- so you shouldn't have a penalty from that either...
UNLESS for some reason you aren't proficient in bucklers -- most rangers are though. The only archetype I'm aware of that does away with shield proficiency for rangers is the Nirmathi Irregular.
The buckler may be what is causing it. I would try to remove the buckler and see if that changes the attack bonus. Alternately, change the strength to 10 and see if that fixes it. Either way you should be able to identify where the program is making an error.
