DDA low Db results

rcprcp

I'm trying to use DDA at a project for the first time, but when looking at the Direct SPL graphs, the meter seems off. One example is with a AWC62 speaker, when simulating it, it shows that we have an SPL(@1m)=90.2dB, but the meter on the right starts at around 70dB (and less). So although I should have 90dB @ 1m, the colors only shows from 70dB or less. Am I doing anything wrong?
