Rick, in the welcome message by Ken it is stated:
"Please remove non-essential parts until you have the minimum scene file
that will reproduce the problem"
I managed to reduce your two files of 180 lines in total to just 19 lines
and to remove several non-essential parts like reflection and specular
highlighting, so you obviously did not try to reduce it yourself. Please do
that in the future.
The reduced scene is in the end of this message.
Note that if you follow the basic old advise of keeping transmit+filter
below 1, then your problem with the yellow thing disappears. When not
following this advise, you should expect strange results.
That said, your scene shows a different bug which I will investigate
further.

Nope, it wasn't a bug after all, so there's absolutely nothing wrong.
BTW, I see that when I posted the code somehow the "{" got lost after
"material" and after "texture", but that's easy to fix...

so having output_alpha=on in the ini file combined with transmit / filter =
1 resulting in a weird effect normal and expected?

You used a filter value of 0.6 and a transmit value of 0.8.
0.6+0.8 = 1.4 = strange results.
As I said, if you keep the sum of filter and transmit lower than or equal to
one, then you don't get any strange effect.
