J-BusinessDirectory - Bug price description

The "price description" field seems to have a bug.
When I try to translate to the different languages on my site, it only saves the admin language.
It is not possible to leave this field blank, so I just put the horizontal line. But, if I edit the pack again, the field gives me back the initial content !!

The issue has been fixed in the 5.6.8 version that can be found on your store account.
