Hi @suzumosh, thanks for reporting. The file has the Menu/Tools/Cell contenss/Autocalculate off, activating it or doing a hard recalc [Ctrl+Shift+F9] solves the issue. As 4.2.8 is end of live no more patches for it. In any case works fine 4.4.4.3, so resolved as worksforme, please if you are not agree reopen it.
