Should all This PC locations be listed in Shell?

Hi all. I love to customise my PC and I've been using programs like Rainmeter and This PC Tweaker for that. I have a slight problem with the latter and I thought maybe someone will be able to help.

This application allows you to edit This PC contents by adding or removing folders to it (i.e. Desktop, Downloads, Pictures, Music etc. + you can add your own ones). I accidentally removed all of the items from This PC, the Tweaker has an option to restore defaults, and it did:




Only some of them are shown in the actual application though. Pictures, Videos and Music are missing from the list:




I can add Shell Locations to the list using this program and I thought that the missing ones would be there (as the other ones like Documents etc.) are listed in Shell Locations:



So should the missing ones be listed there as well? (They are not!) And if so, how can I add them back?

OK, I figured this out earlier on - it's because the locations in question are on a network drive, and that won't show in TPT. False, alarm, can be closed.
