#VALUE! instead of the string in the cells

I’ve found quite ridiculous bug. I use array functions to create index and get the values recalculating the data in the neighbouring columns, eg

=INDEX(A:A;MATCH(1;(C:C=1)*(F:F="0123 456 789");0);1)

When saved, closed the document and opened again some of the cells contain #VALUE! value instead of the resulting string.

Looking at the formula I see that it changes to:

=INDEX(1;MATCH((C:C=1)*(F:F="0123 456 789");0);1)

I tried to play with it, saving the formula in other cells - that helped strangely, but not for other sheets containing the same formula.

Are any workarounds to use there?

Hello,
Please provide the file populated with data that you use for function testing with function itself positioned.
Also, clarify which version of the Document Server do you use?
