I just released version 2.10.https://dev4me.com/modules-snippets/opensource/socialbaker/
The double /pages/ofa-parent/ in the link (canonical and og:url) was a bug (only when not using shorturl) that is fixed in this version.
This new version has a few other bugfixes like special characters handling in page titles.
As extra it ouputs a rich snippet for Bakery product pages with item details and pricing info.
So, just try this version.
I was looking at your website (assuming that was where the problem was) and I noticed you call openGraph() twice.
The first time with the first parameter "true". Your website is not using shortUrl so you should not do that. Facebook will get very confused
Just use the <?php echo openGraph(); ?>
You can also use a second parameter that will show the page title (and metadata description, and used language). For OFA/Bakery pages it will use the item-title instead of the parent page title.
When "1" is used, the title will be "Page title - Website title".
"2" will only show the page_title
"3" will show "Website title - Page title".
I would advise to use <?php echo openGraph(false, 1); ?>
in your website.
