Why is Dolphin in Lost and Found ?

[Linuxguy123]

I use Dolphin a lot and thus I had an icon for it installed in my lower
panel on my KDE desktop.

One day after doing an update my Dolphin icon disappeared.   When I went
searching for the Dolphin application in the application launcher I
couldn't find the Dolphin app in Utilities anymore.  But I did find it
in Lost and Found.  And it doesn't have its icon anymore.

Why did it go there ?   How do I get it back where its supposed to be ?

Thanks
