Solid Steel Saddles for a Cutlass?

I have this issue with my Cutlass where there is this slight zingy kind of buzz on the D and G strings, primarily on the lower frets. I had the guitar professionally set up and pleked and hoped that would fix the issue but it did not. The action isn’t too high at 4/64 at the 12th fret. Raising the action or adding relief to the neck does not fix the issue. Nor does lowering the pickups. I did try putting a piece of paper under the saddle of the G string tonight and that seemed to help some so it makes me wonder if the saddles are where the problem is. Also, I use the same strings (D’Addario XT 9-42) on my Valentine and it does not have this issue.

So…I’m wondering if moving away from the bent steel style saddles to the solid steel style might help. EBMM sells these but I’m not positive they are compatible. Do you happen to know if they are? Do you think this could fix the issue?
