Panelizer error

Hello,

When i open two particular nodes I get this error:

"Notice: Undefined property: stdClass::$display in PanelizerEntityDefault->hook_entity_load() (line 840 of /var/www/{...my...site...}/profiles/sl/modules/contrib/panelizer/plugins/entity/PanelizerEntityDefault.class.php)."

The difference in the error on each node, is the line number in the parameter inside the parenthesis.

I have searched to no avail for information regarding this error, but what I have gotten are similar cases, but not a display problem in the Panelizer module.

I noticed the error after I updated the Views module. The error might have been there before, but no one had reported it.

After updating the Views module, and seeing the error message, I decided to update the Panelizer module, but the Panelizer update didn't make a difference.

To update both the Views and the Panelizer module, I used drush in an vangrant VM under Kalabox because we are hosted in Pantheon.

I checked in Pantheon , in case they had neglected to secure the .htaccess file, but they are secured. So, at this point I have run out of darts and I don't know what else to shoot at.

Core and Ctools as all as any other module in use is updated at this point. The only module requiring an update earlier was Views (which I updated , right before I found about this issue).

Any suggestion about how to get rid of the error will be greatly appreciated.

Thanks.
