Please, for the love of Satan or whoever, do not waste the time of anyone working on LibreOffice with problems you had with Fountain 1917.
For licensing reasons and because I am lazy, Fountain 1917 is missing a lot of things that would be present in a real installation of LibreOffice Calc. If you actually want a spreadsheet application, I would strongly recommend downloading and then using the real LibreOffice.
If something has gone wrong with Fountain 1917 specifically that is reasonable for me to fix, you
can contact support@somnolentsucculent.studio
