JCEPro 2.9.22 (also 2.9.20)
It creates a new profile with the correct name (Copy of...) but all parameter settings are missing.
E.g. Editor Parameters/Filesystem/File Directory Path, Upload settings....
or Plugin Parameters
all is empty resp. default settings.
The export XML file contains all the custom settings but it seems the only thing which is copied or imported is the "Current Editor Layout".
