It sounds like something went wrong during the original installation or when you clicked on Install from the CL App Manager to install a recent update. No updates are made automatically, so you always have a say in whether/when to update the program.
I've not encountered this issue but others have (as shown in the posts PDM shared), and it's good to know that uninstalling/reinstalling restored your custom titles. Hopefully this won't be a recurring issue with future updates
