The LPF graphs give the impression that the LPFs aren't working, that there is a short bypassing all the LPFs regardless of the band selected.
One check would be to look for the 3rd harmonic being transmitted.? Do you have a receiver with a waterfall display? A SDR perhaps?? Try a test transmission into a dummy load and see if you can receive it at the fundamental frequency and 3 times that, for example 7.074 MHz and 21.222 MHz.? The dummy load will probably radiate enough that you can receive the signal locally.? If you get a significant signl on the 3rd harmonic then the LPFs aren't working.

Difficult to see why, other than some major miswiring.
