Frequencies using numerical gradients

Dear Molcas Experts,

It seems that when I calculate frequencies (&Mckinley) using numerical gradients I get only those which belong to the totally symmetric irrep. Is there a way to instruct the program to calculate all frequencies?

I am not sure if its important but I am using cholesky decomposition in &Seward and I checked (at rasscf level) with and without cholesky and saw the above behavior. The symmetry group I used is C2 (XY).

Thanks in advance.

Best,
Shachar
