I am running some models to test the UV contribution from the post-AGB stars to the emission lines of a galaxy. To test this, I use SSPs at the age of 3Gyrs (also tried for 0.1Gyrs and 5Gyrs). Models have no attenuation. The SSPs have solar metallicity. I test 3 separate instances which all have the same parameter values, except that each time I change the pAGB fraction to be 0, 0.5 and 1. I can see that I get ionizing radiation by turning on post-AGB stars.
The problem is that I get emission line fluxes that are all 0. Shouldn't this UV give emission lines forpAGB = 0.5 and pAGB = 1 ? Am I missing something obvious here?

The srcipt I run is the following:
