DataSet as a Ticker in Xibo 1.5.2 doesn't work

Hello Guys,

I created a simplу dataset with 4 columns as follows:
1) Date;
2) Time;
3) Booked;
4) Available;

added data and added a ticker in the system for the dataset. The problem - in the browser it shows error in preview as follows:
PHP Notice: The query [SELECT `Date` FROM ( SELECT `Date`, `Time`, `Booked`, `Available` , RowNumber FROM ( SELECT MAX(CASE WHEN DataSetColumnID = 1 THEN `Value` ELSE null END) AS `Date`, MAX(CASE WHEN DataSetColumnID = 2 THEN `Value` ELSE null END) AS `Time`, MAX(CASE WHEN DataSetColumnID = 3 THEN `Value` ELSE null END) AS `Booked`, MAX(CASE WHEN DataSetColumnID = 4 THEN `Value` ELSE null END) AS `Available`, RowNumber FROM ( SELECT datasetcolumn.DataSetColumnID, datasetdata.RowNumber, datasetdata.`Value` FROM datasetdata INNER JOIN datasetcolumn ON datasetcolumn.DataSetColumnID = datasetdata.DataSetColumnID WHERE datasetcolumn.DataSetID = 1 ) datasetdatainner GROUP BY RowNumber ) datasetdata ) finalselect ORDER BY `1`] failed to execute. Unknown column '1' in 'order clause' in C:\Users\Public\Work\websites\signatact.com.root\xibo.signatact.com\lib\data\dataset.data.class.php on line 321

Any idea how one can fix it?

Thank you, Vlad.
