Unless you're using an above-standard point buy or house rules, those ability score modifiers are suspiciously high. My guess is that you're basing your expectations on the modifiers HeroLab shows on the Abilities tab? In that case, you are seeing them with half-level already added. (So your neutral scores (10 or 11) will show as a +4 modifier at this level.) Assuming standard point buy, your actual modifiers are between -1 (8 or 9) and +6 (22) at this level.

It's a bit of a weird behaviour by HL, since the game rules are clear that "modifier" is just the ability score component of that bonus. I expect the logic is that it's more useful at the table, since most places where you need only the modifier are pre-calculated by HeroLab.
