Issues Queues : Invalid due date format

[geraldine g]

I've created a queue with for instance the following fields : 

- issue type 

- assignee

- due between 26/05/2020 and 26/05/2020 

When switching in JQL , due date is : due >= 0020-05-25 AND due <= 0020-05-25

Date format has changed from 2020 to 0020 and day 25 instead of 26 ? 

It seems there is an issue with JIRA calendar , but i have no clue how to solve it.

Thanks for helping
