Hidden rows acting as validation [JMP]. How to deactivate it?

Question

I am trying to get a predictive model in JMP (not the PRO version).

Some of my rows are now configured as validation data set, but I do not know how I activated this!

For example, when building partition trees I always get the option Go, even without having configured the the k-fold method I want.

Is there a default role that I activated by mistake in my rows?

How can I remove this option from both JMP and JMP Pro?

I think I found the issue.

Excluded rows are considered as validation data set.

I always believed that excluding rows removed these data points from any operation.
