Let's make one thing clear: if there's any issue with your translation, it's because you did something wrong. We now have over 100 versions of it working perfectly fine, and they were built with the exact same material and shared on the exact same platform. The game is fine.
This said, I obviously understand your frustration.
What I would do if I were you is to stick to a basic Windows+Excel machine, download the localization kit again, double click on the CSV file, paste the translation inside it, carefully proofread each line, save and upload the zipped folder to Itch.io
It seems to me that something in the finer details of your LibreOffice save didn't work well, and this will fix it once and for all.
And please let me take this chance to repeat that you can always update your entry, as stated in the FAQ.
