When you export an Idea instance that has an effort task ("~rmw") using XOG, if the Idea instance does not have any Start and Finish dates set, the task has the min/max dates set (such as in year 1900 and year 2079).
(relevant XOG output parts):

The Idea instance does not have Start/Finish dates, but Tasks and Assignments require those dates.
This is working as per the intended design.
If you set a Start and Finish dates to the Idea instance (although they are optional, it is strongly recommended for Ideas to have values for Start/Finish dates), the effort task will inherit the dates from the Idea instance instead of setting the min/max dates.
