I checked your attached configuration and show command output. I did not see problems with the configuration.
The first message, Mars-sigdef-delta.xml not found seems cosmetic issue in your case, since the 'show flash' command does not list this file. This delta.xml file contains all your signature changes which are different from the default Cisco signature configuration. If you do not have any change, then you should not see this file on the flash. In your case, it seems the router is trying to find this file. (I think you were seeing this during a router reload?).
The INVALID_TYPEDEFS is a info message you can ingnore here. Since the typedef file already loaded in your case.
I need more context when you see those types of messages. Do you see these messages during reboot? or during some configuration task, such as load signature pkg file?
