Some flags not working in shortcode?

Hi there, I have a shortcode on my site.
The weird part is, it works for HU, IT, ES, PL, RO,

but does not work for: UA, CA

Here is the shortcode:

function custom_shop_image_container(){
        $flag = get_field('country_of_origin');
        echo '<div class="inner-img">';
        

        // if ($flag != null) {
        //         echo $flag;
        // }

        if ($flag == "Magyarország") {
                echo '<div class="country-flag">';
                echo do_shortcode('[svg-flag flag="HU"]');
                echo '</div>';
        } elseif ($flag == "Olasz"){
                echo '<div class="country-flag">';
                echo do_shortcode('[svg-flag flag="IT"]');
                echo '</div>';

        } elseif ($flag == "Spanyol"){
                echo '<div class="country-flag">';
                echo do_shortcode('[svg-flag flag="ES"]');
                echo '</div>';

        } elseif ($flag == "Lengyel"){
                echo '<div class="country-flag">';
                echo do_shortcode('[svg-flag flag="PL"]');
                echo '</div>';

        }
        elseif ($flag == "Románia"){
                echo '<div class="country-flag">';
                echo do_shortcode('[svg-flag flag="RO"]');
                echo '</div>';

        }
        elseif ($flag = "Amerika"){
                echo '<div class="country-flag">';
                echo do_shortcode('[svg-flag flag="US"]');
                echo '</div>';

        }
        elseif ($flag = "Kanada"){
                echo '<div class="country-flag">';
                echo do_shortcode('[svg-flag flag="CA"]');
                echo '</div>';

        }
        elseif ($flag == "Ukrajna"){
                echo '<div class="country-flag">';
                echo do_shortcode('[svg-flag flag="UA"]');
                echo '</div>';

        }
        elseif ($flag == "Afrika"){
                echo '<div class="country-flag">';
                echo do_shortcode('[svg-flag flag="UA"]');
                echo '</div>';

Can you help with any ideas as to why this might be?
