Validator in create issue transition causes the issue number sequence to be incorrect when creating an issue inside Backlog view

Issue Summary

When you add a field required validator inside your workflow, if you try to create an issue using the backlog view, after hitting the enter button the create dialog box will be shown and the counter of the issue number will be automatically increased by one, once you add the information inside the required field, it will create the issue, but the issue number will be incremented twice. If your last issue was 2, then the newly created issue will be 4.

Steps to Reproduce

1. Add a required field validator inside your jira software project workflow.
2. Follow the steps in this recording

Expected Results

• The issue number should not be increased unless the issue is actually created.

Actual Results

• The issue number is increased each time you try to create the issue without filling the required information inside the full dialog box.

Workaround

• The current workaround is to edit your field configuration and make the field as required and remove the validator from the workflow. 
• Here you can see the steps to remove the validator from the workflow and to edit the field configuration.
