Why am i getting CoderInfo properties warnings?

I am getting a bunch of warnings and am not sure i understand the significance of or how to resolve them....

The CoderInfo property is being set with a Simulink.ParamRTWInfo object when a Simulink.CoderInfo object is expected. Simulink will attempt to copy over property values to the existing CoderInfo object. If you receive this warning during MAT-file or model loading, please resave the file [234 similar]

fyi: i did re-save the file and most of my work is in simulink. Looks like it may be a leftover from the rtw to embedded coder leftover...any help would be appreciated. Thanks!
