Looks like the dummy load is not good or you have a lossy connector
etc.
Change the interconnecting coax cable and see.
A photo of the dummy and interconnect will help us!

Hey all,
Well me and a fellow HAM from my club have made some more progress into
building the W8TEE antenna analyzer. Finally the right diodes came in and
the build is finished.
However on connecting my dummyload to it we are both seeing some very
strange responses into a measurement from 1 - 30 MHZ as can be seen in
the picture.

Any ideas welcome as to what would cause this behaviour. We did perform
some measurment and the it seems the values measured on the board are
fine which makes me believe it might be code related? We tried both Teds
code(1.06) as well as the I believe the latest code by Jack
(1.08).
As allways any tips, hints or tricks greatly appreciated.
