I develop my E-6 in Jobo 3005 drum mostly without any problems. This time I must have had some moisture in one of the drums as the magenta film back layer has not washed off, see attachment.

In B&W this can be cured by placing the negative in the fixer again. How can you cure this E-6 transparency. I am using Tetenal 3-bath process chemicals.
