Design Studio - Cross Tab / context menu deploy error

Hi,

1. I have a simple dashboard with a crosstab and one data source pointing to SAP BW.
2. I deploy the dashboard to the BO Server.
3. I right click on the context menu and get below error.
4. But I first scroll up or down followed by right clicking the context menu, the menu shows without error.

Any experiences or suggestions with this problem?

Kind regards,

/Kim G.
