When you import a k file into LS-DYNA stage, LS-OPT does a basic check for missing *database cards in the k file for corresponding responses defined in the stage. This is just a precausion to alert the user before job are submitted. If you are sure these cards are available or will be part of file dumped by LSPP stage and resulting binout file will have required matsum, nodout data after analysis, you can disable this check (open ls-dyna stage > advanced options > uncheck "do basic check for missing database cards").
