I created 4 custom post types : 'dissertation', 'subject-free', 'subject-imposed', 'curriculum-vitae'

I have created a metabox that I want to display on 3 custom post types : 'dissertation', 'subject-free', 'subject-imposed'.

When I want to create a post on 'curriculum-vitae'. I got an error : Error: An error occurred while running 'mapSelect': Cannot read property '_metafield_presentation' of undefined

I am having a table called "Table", in which there is a list of items with prices - when pressing a button, I would like to transfer all data to another result Table in the same workbook, where you get listed all items from the database and the items from the list and gives out the difference of income and costs as a =Sum Function

It works just fine in Excel, but I would like to have a macro for Libre office calc so I can do the same in Libre Office too.

Hint: I uploaded 2 screenshots of the as-is state and the target state
If you need further code, I could edit my post for you

I have an application which saves CSV files. When I import in Libre Office 5 and save again as CSV, the resulting file will not contain a field separator at the end of the last field. I could use an awk script but is too hard to use for other users. Is there any setting in libre office which will allow me to import and save the file successfully?

I am trying to get the second last value in each row of a data frame, meaning the first job a person has had. (Job1_latest is the most recent job and people had a different number of jobs in the past and I want to get the first one). I managed to get the last value per row with the code below:
