The new parameters for the design acc. to Eurocode 3 like Wy,pl are not yet available, the parameter file was not updated.
If no own profiles, geosynthetics and/or soil layer suggestions were defined, the parameter file may just be overwritten by the latest version (otherwise please send a message by email and have the new basic file dcpara0.dyx sent from DC-Software):
Download the new parameter file dcpara.dyx from the Download Center under Single Download - Configuration files and copy it to your configuration directory (see in the program under Settings - Directories - Configuration directory). Delete the file dcpara-u.dyx in this folder.
Then, when starting the program again, the new parameters are available.
