ChatGPT doesn't want to show me links from knowledge base

Hi everyone!
We are creating a chat-bot, which takes all information from our own base of knowledges. Some of articles from this base have links on web pages. Also we wrote in prompt, that bot must not link to items from the base, because clients can’t see it. And sometimes the bot generate good answers with links, but sometimes he generates smth like “you can read more about it on the project page.” or “If you would like to know more about the project, you can follow the links above.” and doesn’t write links!
Please, help! :sunny:
