Processing Lomography Peacock transparency 110 film

I have a question for those of you who a) process your own E-6 film and b) use Lomography Peacock colour slide film, also Lomography Orca Black and White film.
As you can see from the photo, the clear areas of the film ( this is Peacock) have a distinct yellow brown tinge which causes the image to take on a colour cast of a similar hue. The brown area on the accompanying picture was not exposed to light, the clear area was.
I find the same thing with Orca, although grey in colour, reducing the contrast of the image.
Two questions then:-
1) am I processing the film wrongly? My 35mm E-6 films all process without this issue.
2) have any of you had similar issue?
Appreciate your input on this.

the B&W, Like most B&W films is proably on a grey base. that should not have any detrimental effect on the contrast. (your print expsure will just be the same as a clear base with a less Bright Bulb.

as for the "Peacock" film, they mention that it is intended for Cross Processing in C-41. that is almost always a "code word" for slide film with a colour cast of some type.
