Saving the intermediate status in the documentation tool

At first I have to say that H5P is a great tool we are excited about using it in our LMS on the AI Campus. There is one question about the documentation tool which came up from our content developers though. In one course we are using the documentation tool as a learning portfolio which meant to be used in a way that our learners fill out the portfolio step by step while going through the online course. The problem occurs that learners basically need to fill out the portfolio completely and download it because an intermediate status is not being saved. All information in the tool is lost as soon as I close the browser and reopen it. Is this maybe a problem in our LMS or isn't it possible that it is saved and that it needs to be filled out compeletely?
