HeroLab is very useful, but you need to be careful when you buy items. It sometimes makes mistakes with the limits due to Fame.

It doesn't take Fame into account as far as I know for purchases, but it gives you a convenient place to check what your limit is. On any Pathfinder Society- or Pathfinder Society CORE-configured character go to that character's journal tab (the one where you input your chronicles) and look to see their current Fame, Prestige and expenditure cap near the top. If you hover your cursor over the character's fame score it will give you the table that shows what you can spend at any given Fame total.

There is an actual setting in Hero Lab. With the character in question open click on the Character tab at the top of the window, then click Configure Hero. A window will pop up. Scroll down in the setting frame of that window until you get the Pathfinder Society options (the second one should be for CORE characters) click it and this will eliminate the non-CORE options from your choices and notify you if you have any unCORE options in effect. Click OK to exit from the Configuration window.
