[Geschlossen] Redis Object Cache in combination with WPML

Background of the issue:
I have enabled Redis Object Cache v2.6.5 from Till Krüss on my website versteckter Link. After enabling the plugin, I encountered issues with adding products to the site. The error messages appeared in Dutch, although the site language is German. Disabling Redis resolved the issue. I suspect the problem might be related to products having the same name in Dutch and German. I am following documentation from https://wpml.org/documentation/support/using-wpml-with-redis-caching/.

Symptoms:
After enabling Redis Object Cache, I couldn't add products to the website. Error messages appeared in Dutch instead of the site's language, German.

Questions:
Why does enabling Redis Object Cache prevent adding products to the site?
Could having products with the same name in different languages cause issues with Redis?
How can I resolve the language mismatch in error messages when Redis is enabled?
