Thomas, I think you'll get more answers if you attach the images. The links you provide can't be seen by those who are not subscribers.

Especially on the first one, is there physical damage where the marks are?
Is the damage across the width of the film or along the length? I don't know how the film is oriented in your Bronica.
Any possibility fixer got on the film ahead of developing?

sorry something went wrong yesterday, i thought i insert the images.

bdial: this is along the winding direction of the bronica (lengthside of the film) and horizontal in the jobodrum if it stands.
about the fixer: when i put the cap on it and a drop or anything falls down the drop has to flow horizontal.

maybe something happent during the spooling on the reel but my hands were dry and the marks are so different.
the big one on the pic 1 the small spots on the 2nd and the one black hole on pic 3.

so now the pics should be insert

and i hope for a solution

thanks for helping

Looks like fixer contamination, sometimes fixer doesn't wash out from around tank lids/seals and can cause a problem like that. I use Jobo 2000 series tanks and it's critical to remove the seal and wash separately.

What happens is the slight traces of fixer dry and crystallise, then when you pour the dev in it's not immediately soluble and the crystals stick to the emulsion and cause those bleached areas as they fixer the areas they come in contact with.

The tell-tale sign is the way a larger crystal has dragged as the first image.
