It woks on 6M because it's near the third harmonic of 20M, the
elements act similar to an array of extended double zepps.
Feeding it is the problem but gain and some front to back should be
expected.

There will be no front lobe. BTDT. There will be a lobe to the NW and
NE if you define the desired main lobe as north. It may end up better
or a lot worse depending on the "reflector", which isn't going to
perform well as one.

The only way triple f yagis work well is if the elements are swept
forward. That pushes the right and left lobes from the straight
elements into the center.
