Why does MATLAB change the name of my ROS 2 custom messages?

For some reason when making ROS 2 custom messges I got an error message that files may not have the standard names.

For example, Gpgga.msg used to be gpgga.msg. After modification the MSG file names are changed.

The reason for the change in naming of your messages is because ROS follows strict rules for message names. See the link below under “Property Naming From Messages Fields” for details:
