It must be a bug,

I can reproduce the error here,
it happens with 5.09, and it does not happen with 5.08.

There is one zero sample in the middle of the center lobe,
not all the time, but it appears every 3 seconds or so in a continuous tone.
It is easy to just listen for the error as it is quite audible.
