Facebook product catalogue title name

[bennik]

Hi every one,
I have few issues that I really hope you can help me with.

I have an Online shop made made with Prestashop 1.7.6.2.
I have no IT experience, so please try to explain me as I was a child J

Finally after many tries, I managed to create a product catalogue in facebook and connect it to my website with Facebook pixel.
However I have few issues:

1) Every item/product on my website has few images, but in the “product catalogue” in Facebook, only the cover image is shown. Why? How Can I fix this?

 

2) In the product catalogue in Facebook, the “Meta-Tittle” is shown as it was the product tittle.
In the Prestashop Back office, in the SEO section of each product, I have the option to write a different “Meta tittle” or leave it empty. If I leave it empty, then in the Facebook product catalogue the “Product tittle” is shown correctly ( it shows the product name ), but as soon I add a text in the felt “Meta Tittle” , this text is shown as it was the name of the product.

How can I fix this? I used the module Facebook pixel to connect the Facebook with the website, and also I used my pixel as data Source for connecting the Facebook product catalogue and products on the website.

 

Sorry for the long explanation . I could not explain in a better way.
I add some screenshots.
