Error publishing workflow due to the workflow contains actions that still must be configured.

[#1]

I exported a workflow from the same site. After I created a new custom list then I imported the workflow. I created the same columns and fixed unknown references. I still could not publish it. It looks good to me. What else I should do? Where are Nintex logs? Thanks in advance.

[#2]

I was able to solve the problem myself- looking for controls which has yellow exclamation mark.
