[2021] Supercharge jump not working

I'm in M Puppis 35347 and I just supercharged my FSD in the neutron star.

In the Galaxy Map, under Route Settings, it says my jump range is 191.67. But when I try to plot a jump to a system that's 183.92 LY away (Synuefe KS-G b44-5 for the curious), the plotter insists on a 4-jump route that ignores the supercharging.

Am I missing something? This doesn't always happen. Some jumps plot using the supercharge.

Thanks!
