Panel Preferences shows the wrong text for items
This is a pretty old bug, and I've alway had it since I used XFCE, back in 2013 I think.
When I go into my
Panel Preferences ->
Items, as I move my mouse inside the box containing the list of items, the text for the list of items there changes to other random items.
The icons are correct however, and
Edit the currently selected item also edits the correct item.
I once tried deleting the file and resetting it, but the bug's still there.
My current version is
xfce4-panel 4.16.2-1 on Arch Linux.
