Primeng calendar won't show the correct value in the field

Hello,

I don't know if it will help you to fix your problem but I think I faced the same problem.

For me the problem was that I putted a [minDate] attribute to the calendar. The calendar value was managed by a FormControl.
When I would like to update the [minDate] value and the FormControl value I faced the problem.
If I tried to change the FormControl value with a value less than the previous [minDate] value then the calendar showed a blank field. After if I clicked on the calendar field the value showed.

To fix it I removed manually the [minDate] value on the calendar with a @ViewChild reference to the component. I set the new [minDate] value after my FormControl update.

Maybe it could help you.
