access level warning message in File edit view

When opening a file in edit view, a strange warning message is showing:

Access level: 0 is not valid. Setting Access level to 'Public'. Please select a new access level and save the record.

It is still possible to save the record. However, I'd like to know where the '0' access level value comes from.

your joomla and flexicontent version ?

Joomla 3.6.5
FC 3.1.1

Thanks!

Hello

This is not a bug, it is just a notification that :
- the file has a non-existing access level

Select a valid access level and save the form

----
It would be a bug only if :
you have added the file --recently-- and you added it with a valid access level e.g. public
and the access level was lost,

otherwise as said above , select an existing access level and save the form

Hmmmm... Bug or no bug, the fact that 0 is showing up in the Access Level select list is definitely weird.

Hello

it is much better than ... the file just not showing in frontend without any warning because of bad access level
