Like stated it's a horrendous install. No one does laps like that and provides a quality install at the same time.
1)Make sure it's a James Hardie. I don't think it is. It looks like Certainteed grain and they where very problematic for shrinkage. There was a lot of players in the game at one point that have came and gone. Hardie normally get's the bad rep since they are so big and get called out to warranty issues all time on product that's not there's.
The material could have been installed wet and dried on the wall increasing the little 1/8" shrinkage that is average to 1/4 to 3/8".
2) While caulking it with DAP might work for a couple years at best it will start to crack and fail soon as well. I don't believe DAP is made to to fill joints. It's more of a sealant and doesn't handle well with expansion and contraction. I might look into using something like color matched quad and fill the joints after painting.
To prevent this?
Keep the material dry while it's on the ground. But the joints snug with no pressure. Use color matched flashing behind them so when they do open up a little they aren't so noticeable.
Material has changed a lot over the last 10 years. A lot of bugs have been worked out of the system. I try to install pre-finished only because at the end of the day it's a better product that primed and paint after hung on the wall.
