Multiple effective indices in Boundary Mode Analysis

I am simulating a simple waveguide. What I want to plot in the end is effective index of modes in dependance on wavelength (frequency). In 2D this seems to be super easy like shown here: https://www.comsol.com/blogs/mode-analysis-for-electromagnetic-waveguides-in-comsol/
In 3D (ewbe) I try the same approach. I set a parametric sweep of frequency but the Boundary Mode Analysis study node only seems to save the neff of the last mode (ie. 8th mode if my Desired number of modes is 8). I can get all neffs for all modes if I dont perform the Parametric sweep and in Solutions instead of using Study 1/Solution 1 I use Study 1/Solution Store 1 which saves all the mode solutions.
I cant find anywhere reason why those solutions seem to get deleted in Parametric solutions.
Best, T.
