That´s because the filter is only transformed in frequency but not scaled in impedance. I didn´t do it because at that point I introduce the impedance inverter to make all the resonators shunt as in the first schematic I shared.
If you are interesting in the theory, I started with the method described in the chapter 8.3 in Microwave Engineering. This is Chebyshev filter of order 3 at fc = 1GHz and the LP prototype I used have the following elements:
g0 = g4 = 1
g1 = g3 = 0.8516
g2 = 1.1032
You can also find the table for frequency transformation in Table 8.6.
