Change exposure canon 600D qith magic lantern 2.3

[renatino]

Hi to everybody,
please help me...
i have a canon 600D with ML 2.3, can somebody explain why if i set everything manual (iso, aperture, shutter) when zoom with the lens happens that there's a little correction of the light. what I forgot?
I hope was clear, if not I can upload a little video for show you what happened.
Thank you so much.
Renato


(I don't know if is important, I don't think but...my lens is the classical 18-55 canon f3.5/5.6
