Hi,

If you open the dialog where you can configure that data to show in the "Information" panel in Dolphin, you will see similar items:
"Modified" and "Last modified at";
"Tags" and "Has tag".

Firstly, I do not understand the difference between "Modified" and "Last modified at". And also, what is the point of making 2 items to show the list of tags?

First, are you using KDE 4.5? If not, please upgrade and try to reproduce.

Last modified at is data that was gathered during Nepomuk's Strigi indexing. The display of both "Last modified at" and "Has tag" should be considered as a bug.

If your tags are not those numbers that are displayed, that is also a bug, seperate from the one above.

If you are running KDE 4.5, then please report these bugs.

I am using a 1 or 2 days old build from 4.5 branch. The numbers are really the tags I have added (just for testing). Will report a bug for "Has tag" and "Last modified at".

It was my mistake. https://bugs.kde.org/show_bug.cgi?id=245103
