Error when creating a project package: Method 'Sdl.TranslationStudio.Packaging.ProjectPackageCreation.PreviewWizardPageControl+ProjectPackageFileListItem.FilePurpose' not found.

Question

I get this error when creating a project package every time I tick the box to select the reference file. It doesn't seem to affect the package, but I'm spooked that I get an error every time. Does anyone have an idea what the issue might be - or a solution? 
 Screengrab attached. I'm using Studio 2022 - 17.0.3.11695 
 
 Thanks!

The issue is caused when adding a file, that was a translatable file, as a reference file when creating the package. If you do not enable the Reference file, for the translatable file, in the package creation phase you won't get that error message and the package is created.
