Problems like this (and problems in general) where the AI responds one second and doesn't another, or other issues with the quality of the response, can be addressed in the System Role.
The solution would be to add something similar to this to the System Role:
When answering:
1. Always respond in English.
2. Only use information from the provided context.
3. Double-check the context carefully to avoid overlooking any details.
4. Answer in short paragraphs, and if it is a list answer in a list format with an introduction and if appropriate a conclusion.
5. If the answer is genuinely not in the context, say: "I'm sorry I can't answer that ...."
The key line is:
3. Double-check the context carefully to avoid overlooking any details.
