Calculated Dimension giving 2 answer

[ciphergod]

Hi All,

Was doing a simple app when i face this issue, 

I am using 2 variables to calculate date using AddMonths function.

The formula is:

=AddMonths([Completed Date],[VALIDITY],)

The issue i am facing is that the formula 'works', when i put this new calculated dimension into a table, it gives 2 rows.

First row just shows me the default Completed Date, and a second row that gives the Completed Date + Validity.

Just want to know what went wrong to give this 2 results.

TIA

=AddMonths([Completed Date],[VALIDITY],)
