Message with maximum numbers of characters is shown multiple times

On my page I use the same gravity forms via shortcode multiple times.
With the top form the user is able to add an entry.
Below this form the user can change previous entries with prepopulated forms.

Theres is the problem, that the message showing the maximum number of characters for a text field is shown multiple times.
I know that this bug was reported and should have been fixed with version v1.6.3.2.
Today I updated to v1.6.4.2.1 and the problem is still there.
See http://yellowcapp.synology-ds.de/concappt/BackendConcappt for an example (be patient...this is my development environment).
You have to login with user: "test" and password: "test.
Below the input field "Name" you can see the multiple messages.
Is there any possibility to download version v1.6.3.2 of the plugin, so that I can test against it?

With kind regards,
Edwin

No, the repeated messages are not shown in the formbuilder preview. They just appear if there are more than one form on the page.
In the example (see link above):
If I delete the users entries, so that there is just one form on the page, the messages are shown one time only, too.
The error just happens if there are more than one form on the page.
Perhaps one necessary information.
I set the form via shortcode ([gravityform id=# name=TEXT title=boolean description=boolean ajax=boolean])

Here is the short piece of code how I add the forms to the page:
foreach($allPosts as $aPost){
$BE_ID=$aPost->ID;
if($BE_ACTION!=$BE_ID){
$del_Link=add_query_arg(array('be_action' => $aPost->ID));
$content_string='[gravityform id="'.$form_id.'" name="Kontakt" title="false" description="false"]';
$content_string.='[button link="'.$del_Link.'" type="icon" icon="warning"]löschen[/button]';
echo do_shortcode($content_string);
}
else
deleteBEPost($BE_ID,$post_type);
}

$BE_ID is a global variable, I save the current post ID in.

As you see I iterate through all posts of a certain type and add the corresponding form to the page.
Via "add_filter('gform_pre_render', 'populate_data');" I populate the data to each form, using $BE_ID to set the data from the correct post for each form. It really works very goods. So far no problem.
The only problem I recognized until now, is the problem with the counter message.
