my mistake, LibreOffice does not switch to a boolean cell format in the columns that require it. The program supports it, but does not do it automatically. Now, a comment from a development engineer... cell formats should not be used that way. It would be absolutely trivial to output a FALSE or TRUE string rather than relying on a specialty cell format like that. All fields should be text fields... There really isn't any reason not to support csv format then as a more universal import/export format. Relying on a single company's proprietary format doesn't seem like a good idea.
Of note, using a text FALSE or TRUE cell works perfectly well on imports because that is what I used before I realized the columns were probably booleans (fortunately I had a real excel program to check it on).
If you are having issues with exports and imports, then check your fields in your spreadsheet to make sure the booleans are there.
