Memory text doc upload

Hi all! I'm using GLM 5.2 for creative writing in Venice. I have uploaded some documents when I started to memory (like master prompt for writing style, character and story bible). Since then, I have amended them a few times - the chat does not seem to able to access the new versions I have uploaded to memory, only the old versions. I need to upload it to the chat directly every time there is a change. Is this a limitation because I'm using GLM, or is this a bug? (I'm on paid plan if that matters)

Thanks in advance
