perfect_foresight_with_expectation_errors single shocks block performs wrong size assignment if more than one shock

I added another shock y to the baseline test mod file and have only one single shocks block for x with learnt_in=2:

var c k; varexo x y;
parameters alph gam delt bet aa;
alph=0.5; gam=0.5; delt=0.02; bet=0.05; aa=0.5;

model;
c + k - aa*x*k(-1)^alph - (1-delt)*k(-1) +y;
c^(-gam) - (1+bet)^(-1)*(aa*alph*x(+1)*k^(alph-1) + 1 - delt)*c(+1)^(-gam);
end;

initval;
y=0;
x = 1;
k = ((delt+bet)/(1.0*aa*alph))^(1/(alph-1));
c = aa*k^alph-delt*k;
end;
steady;
check;
shocks(learnt_in=2);
  var x;
  periods 2:3;
  values 1.2;
end;
perfect_foresight_with_expectation_errors_setup(periods = 7);
perfect_foresight_with_expectation_errors_solver;

rplot c;

I get the following error:

Unable to perform assignment because the size of the left side is 2-by-7 and the size of the right side is 2-by-1.

Error in perfect_foresight_with_expectation_errors_setup (line 72)
    oo_.pfwee.shocks_info(:, :, 1) = oo_.exo_steady_state;

So there is a bug here, because if I remove y, the simulation runs.
