[Closed] Problem with Woomultistore with WPML enabled

Background of the issue:
I have 6 WooCommerce shops linked together using WooMultistore. The ‘mother’ shop and one of the shops use WPML. So far everything has worked fine. Prices, descriptions were synchronising between the shops.

Symptoms:
From a certain point on, the synchronisation started to work only for the shops using WPML. After disabling the WPML plugin on the ‘mother’ shop, the synchronisation works for all shops.

Questions:
Why did the synchronization stop working for non-WPML shops?
How can I fix the synchronization issue without disabling WPML on the ‘mother’ shop?
