Using Calligra Sheets, and testing the financial functions, I end up with wrong results, as the input given to the function helper, misplaces the values in the function. Concretely:
In Sheets the input
=FV(0,1;10;0;1000) ----> 2593,74246 , which is correct,
while the one suggested by the wizard is, finally
=FV(1000;0,1;10) ----> -0,00995462

same applies to FV, PMT at least. (Don't mind the commas, should be dots, it's due to localization, the greek variant is with commas).

For reference, the similar example in Libreoffice Calc is:
=FV(0.1,10,0,1000), and gives the expected result.

Reproducible: Always

Steps to Reproduce:
1.In Calligra sheets, press the function button.
2.Use any of the aforementioned functions, filling in the form that emerges.
3.Check the result.
4.Now, fill it in by hand in the top bar, using the schema I propose.
5.Results are right now.
Actual Results:  
input:
=FV(1000;0,1;10) 
result:
-0,00995462


Expected Results:  
input:
=FV(0,1;10;0;1000)
result:
2593,74246


=FV(0,1;10;0;1000)  should give the value 2593,74246
