To reproduce
Steps to reproduce the behaviour:

1. Add new GEN_KW to poly.ert with all CONST.
   For example: GEN_KW COEFFS_CONST coeff_priors_const where the file coeff_priors_const contains:

a CONST 0
b CONST 2
c CONST 5

3. Run Ensemble smoother with Adaptive Localization which results in this screenshot:

Expected behaviour
Make it clear to users that we are not updating const-parameters.
