SketchUp 2021 Template Location Linking to 2020 Location

As the title says, how can I correct this?

I have already ran the installer as administrator and done a repair.

It seems that the file I’ve been working on was originally created in 2018.

Looking at the File Locations in the PrivatePreferences.json file there is a mix of links to various SketchUp versions.

I’ve created a new file using a SketchUp default template and where applicable the links point to the 2021 folder.
