Does it say RTX5 component itself is missing?
Great! Per the help (in the File, Group, and Component Attribute Icons section), a blue badge means the changes are related to modified default values and comments, but there are no new settings. You should be able to copy the new version in, unless the file is write-protected.
I don't want to get off-topic here. Hopefully you have the original source (including project files) as well as the working binary image and a good diff tool.
