First thing you should do is set up your own equipment profile to reflect your process: boil off rate, losses, mash tun volumes, etc. This will help greatly in making the program be more effective for you.
If you don't have those figures yet, you can use the default settings to start.
Next, download the recipe you want to brew. Use the 'scale recipe' function to change the equipment profile to your custom profile. Make sure that the box is checked off to 'match original gravity, color and bitterness.' Change the batch size to match what you want to put into your fermentor and click OK.
This will reset water volumes, adjust the grain and hop requirements to match your process.
After that, look at his mash profile and adjust that to fit your intended mash schedule. Everyone has their own way of doing things: mash times, ramp rates, infusions, water to grain ratio, sparging method, etc; and you want to have the recipe reflect what you do.
Now the recipe should be closer to what your process would product.
I would very much encourage you to take measurements of gravity and volumes throughout the brewing process. You can use those figures to customize your profiles further. Generally, it has taken about 3 to 4 brews of consistent measuring to get a new equipment profile (for a process change I created) 'dialed' in so that it accurately reflects what I am most likely to produce.
Remember also that this is a program. It responds to the information you give it and should be adjusted to reflect what you want to do. The equipment, mash, and fermentation profiles that came with the program are intended to give you an example of different methods and processes. They do not reflect how you should brew, but should serve as templates for you to adjust as needed.
