I have worked considerable time with the report designer. But this is the first time encountered this issue. I modified the AR631000 report by adding some new columns. It worked nicely in the preview. But when I'm trying to publish the report as a new version by “save report on saver” option, process is getting successful without any error. But the new version is not in the instance. Please check the below images.

User access also rechecked by me. It is also in fine status.

Can you please give me guidance to overcome this issue?
