There is a difference between !isset and empty in PHP so while your code is looking at isset vs !isset but your description is saying empty or not empty.

Your field 'exp-date' can exist but have no value in it meaning it is empty.

Your second statement could be changed to check if the field isset and empty

if (isset($fields['exp-date']) && (empty($fields['exp-date'])) {
    echo (new DateTime('+1 month'))->format('d.m.Y');
    $timeset = '';
}

You might find this explanation useful , particularly the table that shows the different states, https://www.virendrachandak.com/techtalk/php-isset-vs-empty-vs-is_null/
