In mailchimp.module > mailchimp_mergevars_populate, there is the following code ...
if (!empty($mergevar_value)) {
$mergevars[$bundle . ':' . $id][$key] = $mergevar_value;
}
I get why that was envisioned as advantageous, but if one needs to clear a value that was previously set, it prevents the ability to do that.
I think we could get rid of that empty check altogether, but if that is really required for a reason that isn't clear to me yet, then perhaps it would be better to do something similar in _mailchimp_lists_subscription_has_changed?
Remove the check so that existing values can be removed.
Polish up the patch, test, review, etc.
