macOS Mojave stacks not grouping by type I have updated my MacBook Pro (15-inch, 2017) with macOS Mojave and everything is woking as per the need.

But I think new feature of macOS Mojave called Stacks is not working properly on my MacBook when I set Group Stacks By to Kind. 

It just create one group with name Other and puts everything (Image, Doc, ZIP, Video) in that one group. 

I tried changing Group Stacks and restarting my mac but no luck.

Is there any other setting for this which I am missing?
I have same issue when I change System Preference-&gt;Spotlight setting. 

From Monitor App, I found Spotlight progress takes a lot of memory, so I disable some options from Spotlight setting's *Search Results*, and then Desktop Stacks with those types disappear.

So, re-enable the expected type in Spotlight setting, the type will show on Desktop.
