Template doesn't start new file when library grouped by "Custom group"

Thanks @MzansiLindsay I can't say I'd noticed this because I haven't got any templates, I never seem to reuse stuff I make! Anyway, I made a template to test this odd behaviour. 

In both Chrome & the Windows app a template does not open a project if the chosen sort mode is custom. There is no 3-dot menu. In Chrome right-clicking the template image does still bring up a menu where you can select Edit in Adobe Express. In the Windows app the right-click option to edit in Adobe Express is missing when in the custom sort mode; it is treated simply as an image in a browser. 

Changing the sort mode to type enables the 3-dot menu and when the template image is clicked opens the pop-up window to start a project.
