Laravel 5.6 - Illuminate\Support\Facades\Cookie::get() return encrypted cookie value

Still "new" to Laravel and encountered a unclear situation.

According to this previous S.O. post Laravel - How decrypt value of cookie, Laravel does automatically decrypt the value of a cookie when using the Cookie::get('my_cookie') command. But in my case it doesn't. I have to use the \Illuminate\Contracts\Encryption\Encrypter class to specifically decrypt the cookie as below.

$encrypter = app(\Illuminate\Contracts\Encryption\Encrypter::class);
$encrypter->decrypt(Cookie::get('my_cookie'))

It also mention I may need this in case I did encrypt it somewhere else. All I did to create the cookie, was invoke the Cookie::queue('my_cookie', 'blah blah', 1000) command.

Any thought on why I may be forced to use this Encrypter class to read the cookie value?

Thx,
