Hoping someone can tell me if something changed in the knowledge base recently - I'm new to botpress and had created a knowledgebase about a month ago. Used website and documents - I had added about 100 URLs which were indexed and then about 30 pdf documents. All was working fine. Came back today to continue along and add some more web pages and documents, but when i look at the knowledge base i created, I can't find anyway to add more URLs or documents to the website and documents areas i had previously created. I can click on the menu bar and add another website or another document, but I can't seem to add anything under the structure i had previously created. Did something change in the last month and now you have to add URLs and documents at the top level of the knowledge base instead of under a header?
