[Openspace] Bug in Field Calculation?

[Agustin Lobo]

Dear list,

Using grid100s.shp,
I've added a new column (say, LAGZAR09)and created a Lagged Variable
of ZAR09. Now, I add
one more column (say, LAGZ) but, as soon as I click Apply the name
of the result automatically changes back to LAGZAR09 and get the 
previous values overwritten and column LAGZ remains empty. Is this a bug 
or am I doing something wrong?

Thanks!

Agus
