NZ AIM return

I'm setting up an AIM return in AccountRight for the first time ever. This is AIM only, no GST. 

The FYE is 31-03-2027. 

When I get to the end of the setup, I'm only presented with Sept 25 to March 26.

Does anyone know how I select a month in the current financial year? 

I tried closing the previous year but still get the same choices.

I tried changing the GST period manually to May 2026 but that made no difference.  

This is what I am presented with.
