Bulky not saving

When updating the description using Bulky I have used the text tab.
The issue is with the last div where there is a link to beeboohecards.com

See code at the end.

When I add the target=”_blank” and save the change, it doesn’t save. When you clear the cache and go to the front of the site and go to the product there is an issue.
When you click on the Click here link it is going to the redirected page but in the same tab, not in the new tab.
The only way I have found for this to save is by going to the individual product on the main WooCommerce section and update the text tab and save it. This then works fine.
Example of an entry I updated the code on the product.

With a few thousand products I need to be able to update the description in Bulky and for this to save and the link to work correctly.
