Issue Summary

State mappings are duplicated in the settings of a Next-Gen project integrated to JA if the program assignment is changed.

Steps to Reproduce

1. Create 2 Programs A and B
2. Create a story value stream for each and several process steps for each story value stream.
   
3. Integrate a Next-Gen Jira project to Program A
4. Configure data pull and wait until the Jira states appear in Next-Gen Settings of the project.
   
5. Update the Next-Gen settings for Program A and set the story process steps and click save. (this will now populate tblJiraCustomSetup)
   
6. Now, change the program of the integrated project to Program B and click save.
   
7. Select the Next-Gen Settings again and now update the story Process Steps (It got cleared because the NG project is re-assigned to a different Program with different Value Stream)
   
8. Click save and close.
9. Navigate back to the project and check the Next-Gen Settings

Expected Results

Jira states should not be duplicated.

Actual Results

Some states are duplicated.

Workaround

Currently, there is no known workaround for this behaviour. A workaround will be added here when available.
