## Description

### Steps to reproduce

1.  Login to QA Edge
2.  Have a calendar widget on Overview page of your project
3.  Create a task which will appear in the calendar
4.  Try dragging left or right on the calendar so that the date changes, or try moving the whole work package to another date.
5.  After the success message, try updating the dates once more on the calendar by dragging left or right or moving the work package.

### What is the buggy behavior?

On 2nd try, dates cannot be changed, there is an error message (please see the attached video)

### What is the expected behavior?

1.  Dates should be changed on 2nd or 3rd try just like they do on team planner or calendar (module).

### Important note

There is another bug with milestones not being able to be moved at all on the calendar so please test this with some non-milestone work package and I will create another bug report for milestones and link it to this WP.
