Layers panel only shows the number of layers

Question

Hi guys,
Apologies if this is a stupid question, but it's been bugging me for the past hour.
Since the last update my layers panel looks like this:
How do I make it show the actual layers list? I've tried resetting the workspace but nothing seems to work
Thank you
Edit: If it helps, I'm using Illustrator 2014.1.0 on OS X Yosemite 10.10

David,
There are some strangenesses with Yosemite reported, but so far no definite pattern.
Anyroad, your issue has been reported in earlier OS versions too, so maybe it is worth going down the list.
The following is a general list of things you may try when the issue is not in a specific file (you may have tried/done some of them already); 1) and 2) are the easy ones for temporary strangenesses, and 3) and 4) are specifically aimed at possibly corrupt preferences); 5) is a list in itself, and 6) is the last resort.
1) Close down Illy and open again;
2) Restart the computer (you may do that up to 3 times);
3) Close down Illy and press Ctrl+Alt+Shift/Cmd+Option+Shift during startup (easy but irreversible);
4) Move the folder (follow the link with that name) with Illy closed (more tedious but also more thorough and reversible);
5) Look through and try out the relevant among the Other options (follow the link with that name, Item 7) is a list of usual suspects among other applications that may disturb and confuse Illy, Item 15) applies to CC, CS6, and maybe CS5);
Even more seriously, you may:
6) Uninstall, run the Cleaner Tool (if you have CS3/CS4/CS5/CS6/CC), and reinstall.
