LearnDash: Cannot add a user to group.

Hi, I cannot add a user to my learndash group.
Here is my email: [EMAIL][email hidden][/EMAIL]
The workflow name: gform > learndash

In my workflow, I have used two learndash action blocks. For 1. To enroll users in the course and 2. Add the user to the group.
So, should I use both blocks in one workflow Or just the #2 block can be used. The reason I am asking the question is, in the #2 block why there is a field named course name
Is the above-mentioned case causing an error

Please see my problem.

Please see my problem.

Please pass the Group Id instead of the Group name and the entry again. And map the user Id in place of the user's name.

Thanks
