Environment

Quite normal env, Mac, Chrome, I don't think this is relevant for this issue.

Angular version

20

PrimeNG version

v20

Node version

22.19.0

Browser(s)

Steps to reproduce the behavior

There is no need for steps, this happens on first load of the autocomplete component, it doesn't use the optionLabel and display the value.

Expected behavior

When selectedCountry is initialized with a value it should display the suggestion label if avaialble respeting the optionLabel property. This means if selectedCountry is pre filled with CA and the optionLabel is provided and there is an entry in the suggestions that match this criteria the input should display Canada and not CA.
