Bug on date input/time input

Hi, guys i have a screen that needs 2x(date input) and 2x(time input).
If i go on
“positioning” →
Position: absolute →
Top: 400px (for example)

It doesn’t show properly, also is not centered and if i click on date/time input it doesn’t let me choose anyting. I think this is a bug because labels/button with same settings are shown on a position but date input another(same positioning settings).
Any tips or is it a bug? Am i missing something? Thanks
