No items can be added to an existing order

We use joomla 5.4.2. and j2commerce. I know that the feature to edit an existing order is in the Beta Phase. If I want to add a new product to an existing order via the Article Number, there is a field to fill out the article number, but no products where find or shown to select. There is also no button like "add product" or something else. I can send you a screenshot if you want, or here is a link to the screenshot which shows the problem:   https://www.dropbox.com/scl/fi/wt9i8x0l73r8zc2r2btsz/26-02-2026_12-35-48.jpg?rlkey=igvr1aluj38adk5y8ew5zr3rc&st=8nbfibiu&dl=0    600-019 is an article number from us, I have tried it with different products, but it does not work. Thanks for checking it, best Regards  Johannes  

Hello Olivier,

thank you for your reply! 

I know that Products (Article number are the sku's), I can see it in our order confirmations in the backend, here are the screenshots:

But if I try to add a product via sku, I do not get a list, see here:

I know this feature from the j2store-cart at "Relations" (in German: Beziehungen), here the same problem appears, there were no products shown:

Thank you,

My webdeveloper found now the problem. 

The JQuery library was only loaded for the frontend. Now it is loaded for frontend and backend, now it works.

Thank you, 

best regards
