Magento 2.4.6
I added a custom product attribute next to the qty in the checkout summary following the tutorial on Add custom product attribute to checkout summary Magento 2.
That works until the second checkout step is opened, as soon as step 2 is loaded, the value disappears. Reloading makes it visible for 1-2 seconds until it disappears again. Step 1 has the same problem now.
The line in details.html looks like that:
<span class="product-item-unit" data-bind="text: $parent.unit"></span>
Any idea whats missing to make it stay?
