Deadline of sprint (from Jira) is displayed incorrectly in Portfolio

[Tuan Lam]

Hi,

I created a plan in Portfolio. Source of plan is from a board. 
In jira board, i have a sprint call as "DEV_H17_BRAVO" and its time is [May 25th - June 8th]. But after creating plan, i have time of that sprint is [June 8 - June 8] as below picture.

What can i do to make sprint display its time correctly? (I already refresh sprint or click on calculate button but the issue is still happened).
