Here is an update on how to export and import TSV file with
Version 3.28.54
. Export as normal, open LibreOffice Calc, drag file into Calc, click OK to UTF-8 format, highlight the relevance column, right click and select column width, resize it to two. While the column is still highlighted, select find and replace, type Array, click match case, and click find all. This will give you the number of 'Array' words that have to be deleted. Highlight the column once again, selecting find and replace, type in Array, and match case should be selected.
Replace All the 'Array' with nothing. Save the file, exit LibreOffice, and the file will import properly back into Limesurvey.
I have used this multiple times with translations, and works like a charm.
