Summary

The action Exclude from Autoconversion is disabled.

Content

I am preparing a demo for a client and I would like to show the actions that an HR specialist can do when converting a Pending worker. I was able to find explanations for the other actions, however, the "Exclude from Autoconversion" I can't find enough information as to why is it disabled in the first place and how will I enable this?

Thanks in Advance
