Updating report specification not reflecting in BI Launchpad

I have updated a report specification using REST service

by issuing put to

http://hostname:6405/biprws/raylight/v1/documents/24183/reports/2/specification

It updated, and all subsequent get requests, as well a getting the report via

http://hostname:6405/biprws/raylight/v1/documents/24183/reports/2/

or any of the elements that were updated

http://hostname:6405/biprws/raylight/v1/documents/24183/reports/2/elements/123

return the newly updated values (in this case updated column names.

However, when logging into BI launchpad, the same document and report still show the old values.

So now rest and bi return different values.

Is there some way to ensure that it is "commited"
