Unable to change access rights for diary

Hello,

With V 4.3.0, a problem occur when i try to change access rights for diary.
In Specific access mode, i try to change any of the value for diary acccess (ie : to grant access for all ressource for managers), but i get the message "no change to save". If i try to do other modification in the same time, i get the message "changes saved", but nothing appends on the access diary line...
