Date picker bundle trouble

[juliensaintmaxent3113]

Hi guys,

in the version November 2018 patch 2, i try to use date picker object from the bundle but i'm suprise to see the operation.

let's tell you the problem.

when i selected a value in the calendar it's impossible to selected a new rangebut it's possible to selected the predefine value.

When the range option is used, all values are in gray.

however, when i clear filter date, it's again selectable.

Any idea of the trouble? it's the smooth running?

Thanks for your help.
