I have found it can take up to 4 days for all of the Layouts to become available via ETL Assistant.
I would not have tried to activate so many Layouts in one go you may find that the java sessions will over
ide one another and the Layouts will not be created, as another Java session kicks in.
If you ever get the chance, I would start over and only add 10 Layouts per day that should give the ETL sessions the chance to load up all of the correct Layout schemas, over the time period specified in the .jar and .properties files.
I’m sure there is more you can do but it was very ambitious to try to load up 42(!) Layouts in one go…
