How can I update cloneable field values?

[MrJoshFisher]

Hello,

I'm having an issue with trying to update the values of a cloneable field, for instance,

Retrieving the value as follows $emails = get_post_meta(123, 'memo_category-103');

print_r($emails); as you'd expect returns Array ( [0] => [email protected] [1] => [email protected] )

I can array push to add a new value:

array_push($emails, '[email protected]');
Array ( [0] => [email protected] [1] => [email protected]  [2] => [email protected] );

But when I save it for example

$emails = array('[email protected]', '[email protected]', ' [email protected]');
update_post_meta(123, 'memo_category-103', $emails);

I get this Array ( [0] => Array ( [0] => [email protected] [1] => [email protected] [2] => [email protected] ) [1] => Array ( [0] => [email protected] [1] => [email protected] [2] => [email protected] ) )

I've tried several different ways to try and rectify this but it doesn't work, I would love to switch to a different meta field plugin but unfortunately, I can't as there are thousands of posts stored using this so I'm having to try my best to rectify it, any help would be greatly appreciated.

Or if anyone else has a solution it too would be greatly appreciated.
