After a fresh installation I see that in the left panel of each surveys don't appear the submenus (see first attached image).
If I look on the db tables "lime_surveymenu" I see that the id field of the three menu (settings, mainmenu and quickmenu) are 5, 10 and 15 instead of 1, 2 and 3!
In the "lime_surveymenu_entries" table I see also that the field "menu_id" it's valued between 1, 2 and 3!
If I change in "lime_surveymenu" table the id value to 1, 2 and 3, then all the submenu appear in the survey!

We use MySql MariaDB Galera Cluster and so we have the following limitation:
https://mariadb.com/kb/en/library/mariadb-galera-cluster-known-limitations/
In particular:

• Do not rely on auto-increment values to be sequential. Galera uses a mechanism based on autoincrement increment to produce unique non-conflicting sequences, so on every single node the sequence will have gaps. See http://codership.blogspot.com/2009/02/managing-auto-increments-with-multi.html

If I look in the function getSurveyMenuEntryData() in \application\core\LsDefaultDataSets.php I see that the menu_id are hard coded between 1, 2 and 3.
The simplest solution is to modify the function getSurveyMenuData() to explicitly set the id of the menu data... I tried in this way and redo a fresh install and now all works fine!
In the secondo attached image you can see the simple changes to the code.

You should check if the problem also occurs in other tables (I don't think so) and in any case you have to take care of this in future developments.
Thanks
