Abandoned Cart Shopify Bundles

Hello,

I have a problem with my abandoned cart flow.

To introduce: I have a website where I sell single items but also bundles (boxes where I sell 6 individual products with a dedicated offer).
I created these bundle product pages via the Shopify “Bundles” application.
In my "Abandoned cart" flow the problem is that I cannot display the bundle product alone in my email with the associated price. This brings me back the 6 articles with a dedicated photo + dedicated price.
When I click on "Preview & test" to try to find the line of code corresponding to my bundle I find nothing.
Here are the parameters I specified:

Abandoned cart image display : 

Link adress => {{ event.extra.checkout_url|default:'' }}

Abandoned cart text display : 

{{ items.presentment_title|default:'' }} {{ items.presentment_variant_title|default:'' }}
Quantité : {{ items.quantity|default:''|floatformat:0 }}
Prix : {% currency_format items.price|default:'' %} {% currency_format items.compare_at_price|default:'' %}

Thanks in advancing !
