Hi, I have simple workbench where outcome is saved as dynamic schema. Somehow, additional columns are added to attribute table of the feature classes in gdb. Any clue what is going on?

This is because these attributes are generated by FME when reading the data. You can fix this in the SchemaScanner, in Ignore Attributes Containing. This should work:
^fme_|^geodb_|^multi_From the documentation:
Excluding Attributes
SchemaScanner processes all attributes on incoming features, including fme and format attributes. It is possible to ignore attributes using the Ignore Attributes Containing parameter.
Enter a regular expression, and matching attributes will be ignored.
For example, if the source data is CSV, you could use the regular expression ^fme_|^multi_|^csv_ to ignore any attributes starting with fme_, multi_, or csv_.
