Description

Issue Summary

When creating or editing issues, if the Target Start and Target End are in the screens, the users can set the End date for a date earlier than the Target Start. Even if the warning: Target end date must be after target start date is displayed, the user can still submit the new ticket / change the existing one.

Steps to Reproduce

• Create a new ticket and set Target End to 10 of December 2025 and Target Start to 10 of November 2025.
• Click create

Expected Results

Given the warning on Target end date must be after target start date, the ticket should not be created

Actual Results

It's possible to create the ticket and also edit existing tickets.

Workaround

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