I still have a question. I read your official documentation that WPML and WP Sheet Editor are compatible, but I use WP Sheet Editor to copy the product from the main language to the secondary language and sometimes images appear, but sometimes the picture will not appear in the secondary language, what is the reason for this?
I can confirm that WP Sheet Editor is compatible with WPML, and I don't see any known issues related to it at this time. However, I cannot say for sure what might be causing the problem you described. Have you followed the guides below to ensure all the steps are correct?
I followed the second link you sent me, and found that no product images were available in other languages. I asked the WP Sheet Editor for technical support, and they said it was your WPML plugin problem, but I don't know how to send my website background information to you, you can enter the background operation once again to understand.
I have created a new fresh site. Could you please try to replicate the issue there and, if possible, make a short screencast showing me the steps you took?
The link to the site is in the following private link.
