Hydra - Non Linear Solution

I am running a transient thermal analysis on the construction phases of a dam.
At the report file at the first analysis under general parameters it has : Nonlinar ON.
At the next analyses under general parameters it has : Nonlinar OFF.
I am using the default interation method (KITE 1) and the analysis is running sucessfully
but why does it says that Nonlinar is OFF?

Hello

without any further information I don’t know why the program changes the calculation from non-linear to linear. Have you seen our TEDDY examples? Perhaps they help you understand the program behaviour.

Unfortunatelly I could not find a solution from the Teddy examples.
My teddy file is as follows: (after i have made the geometry and materials)
I want the LC 1 to be for the grp1 with a specified time function 1
then the LC 2 to be for the grp 1 and 2, where the grp 2 has the function 2
which continiues from the time LC 1 has ended

at the results it has nonlinear for LC 2 OFF but nonlinear ON for the LC 1
What error I am making? thank you in advance
