Error from reading LibreOffice Calc document. With XLSX-format file all good.
If a row in the same neighbor cell contents, while reading only the first(left) read.
For test used fpsGrid example from CT CodeOcean fpspreadsheet.
system Debian 3.16.7-ckt7-1 (2015-03-01) x86_64 GNU/Linux with CT 5.2
Libre Office 4.3.3.2 ID сборки: 430m0(Build:2)
Sorry bad english.

Bug with reading LibreOffice Calc ODS-files using fpSpreadsheet
was fixed developers. I checked ver 1.43 from sourceforge.net/projects/lazarus-ccr/files/FPSpreadsheet/, it works correctly.
In my opinion fpSpreadsheet must be replaced in the next version CT 5.3.

Here Sir
