I just gave the new build a try and I have yet to solve the new puzzles. Maybe I'm screwing up the safe combination but the panel... Wouldn't this be the solution? <spoiler> ...
We will make this more clear in our next update, as many didnt seem to find the connection there.
In the shelf with the books there is a picture on the wall which shows different medical items of different height. You must adjust the books with the right topic on that height and then put the symbols in order of the items on the picture from top to down at the safe.
