Hi!
Maybe there is a bug when using MB Custom Table with Select Advanced fields (multiple).

When I write
$values = rwmb_meta( $field_id );
echo count($values);

It always shows 1 unit more than the actual result.

For example:
I have 2 select advanced fields (multiple) A and B.
- A saves data in postmeta
- B saves data in a custom table.

I choose 2 items for each field when writing post.
With similar echo count($values) code, I get:
- A: 2 (correct)
- B: 3 (incorrect, there are only 2 items)

Hi!
There is another similar issue with Custom Table and Post field with multiple choices:

If a post field saves data to a custom table, it also saves 'i:0;s:0:""' before other items.
I choose 2 posts and this is the data I have in the database
a:3:{i:0;s:0:"";i:1;i:194;i:2;i:197;}

Because of this, when I use this code
```
$post_ids = rwmb_meta( $field_id, ['storage_type' => 'custom_table', 'table' => $table_name] );
foreach ( $post_ids as $post_id ) {
    echo '<p>', get_the_title( $post_id ), '</p>';
}
```
It shows as I have 3 posts, not 2.

This issue has been fixed in the new version of MB Custom Table v1.1.11. I'm going to mark this topic as Resolved.
