Language problem

Am I the only one who is experiencing this? Since I started using Deepseek, from versions like V3, I've rarely encountered issues with language switching or strange outputs, except for the very first time I used it because I hadn't set the language. As I continued using it up to V4, I never had language problems, except for very few and infrequent minor language interjections. And I really liked the expert mode, it was great,. Until the new update that combined all modes together. I was very happy that it happened, but am I imagining it, or has it become slower and worse? Moreover, the language issue that rarely happened to me has started occurring frequently. It replied to me in Chinese .Even though I've repeatedly asked it to respond in English. I want my expert mode back This is all I want to say. Also, my first language is not English. It might seem difficult to understand and poorly translated.
