COLLATE NOCASE bug?

Currently on Android 5.x my app is having issues with an SQLite query. There seem to be an issue with ORDER BY " + KEY_TEMP_CAT_CATEGORY + " COLLATE NOCASE. This is causing my query to exclude some items from the results. Removing this particular part causes the issue to disappear. This wasn't an issue until Android 5.x :(

Any tips or ideas how I can resolve this would be greatly appreciated.

Here is the full query:

// query for total categories
String queryTotalCat = 
    "SELECT _id, NULL as " + KEY_TEMP_CAT_CATEGORY + ", " +
    "COUNT(*) as " + KEY_TEMP_CAT_COUNT + " " +
    "FROM " + TABLE_NAME + " " +
    "WHERE " + KEY_TYPE_FAVORITE + "!=0";

// query for total count of each repeated categories
String queryTotalRows =
    "SELECT _id, " + KEY_CATEGORY + " as " + KEY_TEMP_CAT_CATEGORY + ", " +
    "COUNT(" + KEY_CATEGORY + ") as " + KEY_TEMP_CAT_COUNT + " " +
    "FROM " + TABLE_NAME + " " +
    "WHERE " + KEY_TYPE_FAVORITE + "!=0";

// union the two queries
String query = 
    queryTotalCat + " UNION " + queryTotalRows + " " +
    "ORDER BY "+ KEY_TEMP_CAT_CATEGORY + " " +
    "COLLATE NOCASE ASC";
