**Chance of Occurring (high/medium/low/very low)**

**Pre Conditions: which Env, any pre-requesites or assumptions to execute steps?**

**Steps to Reproduce**
Steps to reproduce the behavior:
1. Go to Names >> Create NR >> Approve the NR
2. Go to BRD >> Find the NR >> register it ,leave it in the tab
3. Go to Names >> Manage My Name Request >> Fill Details >> Incorporate Now

5. Creates 2 diff temp filings
6. File one of them >>> Converts to business

7. Other temp stays in db as a Draft which cant be used

**Expected behavior**
delete the extra filing where nr is consumed, as this cant be used anywhere now.
This is to reduce the possible duplicates for the Org.

Possible Solution:
Filer can check if nr is consumed once business is assigned, delete any other related NR filings.

**Screenshots/ Visual Reference/ Source**
If applicable, add screenshots to help explain your problem. You an use screengrab.

Start by reproducing the flow through Names, BRD, and Manage My Name Request, creating two temporary filings for one approved name request and filing one. Trace where assigning the business number marks the name request consumed and where related filings remain as drafts. Done means the unused related temporary filing is removed and the filed business remains usable without duplicate filings.
