Web Intelligence Issue - Refresh Universe

Hi guys, I have the next issue. When i make changes to the universe (IDT) the webi reports seems to continue looking at the previous version of the universe based on (IDT). Is there any way to clean up buffer or something. Even i have to create a new webi report in order to take the new version of the universe. Please, help me to clarify the issue. Much appreciated.

Regards,

Iván.
