weirdness with yaymail

Hello,

So I’ll start by saying that while I was searching I found out where the problem came from.
I use Yaymail for my Woocommerce messages andWordpress 5.9.2. I have integrated AST to my emails and it works perfectly well! but below the tracking table I have some code that appears:

ul.tracking_list{
padding: 0;
list-style: none;
}
ul.tracking_list .tracking_list_li{
margin-bottom: 5px;
}
ul.tracking_list .tracking_list_li .product_list_ul{
padding-left: 10px;
}
ul.tracking_list .tracking_list_li .tracking_list_div{
border-bottom:1px solid #e0e0e0;
}

Here is a screenshot : https://zupimages.net/viewer.php?id=22/11/4hf1.png

I found the way to remove it from the emails by modifying the tracking-info.php file ( plugins/woo-advanced-shipment-tracking/templates/emails/tracking-info.php ) and removing the following footer code :

<style>
ul.tracking_list{
padding: 0;
list-style: none;
}
ul.tracking_list .tracking_list_li{
margin-bottom: 5px;
}
ul.tracking_list .tracking_list_li .product_list_ul{
padding-left: 10px;
}
ul.tracking_list .tracking_list_li .tracking_list_div{
border-bottom:1px solid #e0e0e0;
}
</style>

But in the next update it will come back. Can you fix this issue?
In advance thank you!
Antoine
