date format issue

I am using pickdate as bundled with MDBootstrap (4.5) - its the current release.
I cant seem to get the date format right. When i click on the field, i get a default date of Nov 30, 1899.

This is the code i am using:

`
$(".datepicker").pickadate({
formatSubmit: 'd/m/yyyy',
format: 'd/m/yyyy'
});
`

``

But i have also tried
`'d/m/yyyy'`

What am i doing wrong?
Thanks!
