Button Row Element Custom Class

I checked the new button row is not showing the added custom CSS class in the HTML
Please fix this in the future update.

For temporary fix.
Change /themes/enfold/config-templatebuilder/avia-shortcodes/buttonrow/buttonrow.php on line 410
From:
$output .= "<div class='avia-buttonrow-wrap avia-buttonrow-{$this->alignment} {$av_display_classes}'>";
To this:
$output .= "<div class='avia-buttonrow-wrap ".$meta['el_class']." avia-buttonrow-{$this->alignment} {$av_display_classes}'>";
