Selected date in input text not change follow the locale.

[ChineseGhost]

Now I'm using ngx-bootstrap datepicker and following this link
https://valor-software.com/ngx-bootstrap/#/datepicker#locales to set locale of the date format to thai date (th-be). Then when I click the input text the calender showing with thai pattern.

But when I select the date, the date text that is show in the input still not change to thai pattern.

But if I test with https://stackblitz.com/, the date text in the input text correct as I want.

Any suggestion.
Thanks

This problem is solved by updating the ngx-bootstrap to 5.6.1.
