The likely explanation for this would either be a flipped
lens element
or as previously suggested, mismatched elements from
different
lenses...
I bought my Belplasca (matched CZJ Tessars from the mid-50s)
from the
original owner. I got it for a good price because, he
explained, the
camera was never right again after he did an interior lens
cleaning.
Sure enough, when I sent the camera to Ken Ruth, he said
that both
center elements were reversed. The camera is now a killer...

The effect on the image from reversed center elements is
not subtle! The elements are very nearly symmetrical so its
hard to spot which side is which by looking at them but the
image effect is very obvious. In the Rollei finder lens its
easy to reverse them. Its useful to make a drawing as you
disassemble the lens in order to keep track of which way the
spacer is supposed to face. It may be a good idea to examine
the surfaces of the center element with a loupe or to
examine the edges to keep track of its orientation.
Sometimes one edge is chamfered and the other isn't.
