This thread is resolved. Here is a description of the problem and solution.

Problem:
You are using a multilingual WooCommerce website with WPML and a WooCommerce bundled products plugin. After recent updates, when you add or update a product in German, the bundled product disappears. Additionally, certain custom fields were set to 'don't translate' which should have been set to 'copy'.
Solution:
First, ensure that the custom fields _wc_pb_aggregate_weight, _wc_pb_bundled_items_stock_sync_status, _wc_pb_sold_individually_context, and _wc_pb_virtual_bundle are set to 'copy'. This adjustment should resolve the issue with disappearing bundled products when updating in German.
For updating all products at once, if you use automatic translation, resend everything to translation. Alternatively, you can use a bulk update feature or a plugin to update the original products in bulk, then switch languages and perform the bulk update again.

If this solution does not apply to your case, or if it seems outdated, we highly recommend checking related known issues, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. Should you need further assistance, please open a new support ticket.

Background of the issue:
I have a multilingual WooCommerce website using WPML. I also use a Woocommerce bundled products plugin. The plugin works fine in the original language, but issues arise when adding products in German.

Symptoms:
When I add a product in German and update it, the bundled product disappears. This issue started occurring after recent updates.

Questions:
Why do bundled products disappear when updating in German?
Is there a known issue with WPML and bundled products?
Do I need to add XML to fix this issue?

The bundled products should be copied from the original. Did you ever change the default language?

No, I have never. changed it. Bundled products were never copied from original language. I had to add them manually and that worked. Since the update (i think) I can't even do that....

If you use the WPML editor to translate them do you still have the issue?

If I provide you with a Sandbox, would you be willing to install WooCommerce Product Bundles and try to reproduce the issue?

Thanks, here you go: hidden link

WPML is already installed, you just need to configure it like it is on your site.

hey.

i found that _wc_pb_aggregate_weight, _wc_pb_bundled_items_stock_sync_status, _wc_pb_sold_individually_context, _wc_pb_virtual_bundle custom fields were set to don't translate. I set them to copy now and it works. this must have automatically happen with the latest update because before that it was working ok.

anyway, is there a trick that lets me update all the procucts at once? I hate to make a minor chanhe to an original product then update translation for each language... it takes too much time.

I have some other issue here, where custom tab (youtube video) is not translated. I can copy the field ok, when I save it it looks ok, but when I referesh the page it goes missing.

here is a screencast

If you use automatic translation, just resend everything to translation and it will be fixed.

Otherwise, you can try a bulk update feature or with plugin. You first bulk update the original products, and then switch languages and bulk update again.

About the YouTube issue, since it's a different problem I'll split the ticket and we can continue there.
