Help !! 3 days for my thesis ! Robustness for independent variables?

Dear Forum,

I have a huge problem. I am running a logisitc regression and for some IVs the assumption of linearity was not met.

Now I need arguments that my IVs are robust to the DVs (I really appreciate you tips, but please do not ask why I need it and I also do not need suggestion to conduct other statistical models). (see overview attached).

I do not know how to interpret the "B" as the variables are transformed. The goal is to find arguments that the B value is relatively small.

As I am slightly running out of time I would be happy when somebody can help me.
