Some old issues are displayed as part of the Leak Period in the Issues page.
How to reproduce:
- with the leak period set to previous_version, analyze a project with some issues introduced in the leak period
- change the project version and introduce a new issue in the code
- after clicking on the link corresponding to the new issue on the project homepage, the Issues page is supposed to display only this issue that was created in the leak period (creation date is set to Leak Period) but it displays some additional issues which were introduced in the latest scan of the previous version.
