silverstripe - SortableGridField causing SQL error -

After a lot of searches, I found: for example usage.

However, implementing it in code results:

[user error] Could not run the query: Select "Sidebar" from the "Sidebar" Inner on "Two column_sidebar" The column 'sort order' is unclear in the "sidebar id" field in the "to-column sidebar" = "sidebar" field list

I am using SS3 and it is installed in SortableGridField (although no message Does not indicate successful establishment) "id" ("Two column_indurbar".) "Do not load CMS" ("server error"), with the "two column IDID" = '2' dev mode running, though, when Dev mode is enabled, I get the above SQL error. However, it is working properly, I have to find out why this error has been thrown.

UPDATE

Below this error, most of the stack marks generated Is up (page 2 [user error] are blue headers):
