shortcode to random number function returns same number

***RESOLVED***
If I force refresh the form page after submitting the form and then submit the form again, I get updated random numbers. I’ll have to force a refresh after the form is submitted to ensure this doesn’t happen.

I have a simple function, and created a shortcode.
———–

function uniquenum_function() {

    
    $uniqueNum = rand(10000,99999);
    return $uniqueNum;

}

add_shortcode('uniquenum', 'uniquenum_function');

———–
When I call the function from a page template and keep refreshing a page, I get a new random number each time.

However, when I add the shortcode into my Contact Form 7 form using a hidden dynamic field and submit multiple forms, I get the same random number every time.

I’m having the same issue if my function returns a timestamp. I get the same timestamp over and over.

Anyone know why the value I’m returning from the function is “sticking” and repeating each time I submit the form? Is this some type of caching issue?
