I want to detect interaction and I use real dataset in paper: Detecting Statistical Interactions with Additive Groves of Trees, but cannot get the same result.

I use the real dataset Kinematics, which use parameters like above.
I split the data, four part is train, the remain one is validation file. The attribute file is like this:

then is the train file:

As illiustrated on the website material, I first run ag_train with parameters like below.

log.txt shows like this:

the parameters are different from illustrated on paper. Then I do the feature selection with the parameters trained model give, it tells only four features are used , so I wonder what problems are in my step.

Thank you.
