Hi ​@Astrid_G, thank you for posting in the community! Taking a look at your screenshot, it looks like you might already have 6 columns selected for your view.

Only a maximum number of 6 columns can be displayed at one time. If you already have 6 selected, one will need to be deselected before you can display something else. 

Default fields such as ‘Modified’ and ‘Created’ can be found in the right details panel when you right-click a document/folder and select ‘Show details’. Since custom attributes don’t appear in the details panel, it may be helpful to deselect one of the default in favour of a custom attribute. 

I hope this helps! Feel free to let me know if you have any questions. 

Thanks Leianne, that explains whats going on.  

Might I suggest having information on that pop-up window to explain the limitation? 

Hi ​@Astrid_G, glad that information was helpful! I agree that a tooltip or pop-up with that information would be beneficial. I will pass this feedback onto our development team for their consideration. 

Would you mind submitting an idea post for this as well? This will also allow other users with similar requests to discover and upvote it, then add details of their own.

Finally, for more information on how Lucid manages feedback via this community, take a look at this post:

​@Leianne C - idea has been submitted.  Manage Columns popup needs info to indicate only 6 columns allowed | Community

Thanks for the update, ​@Astrid_G!
