Controls roles disapearin SAS Visual analytic report

[EFFIK_SAS]

Hello,
I am setting a report but I note that each time the report is reopened, the roles assigned to report controls disappear.
I have parameters in each controls.
However, the tables are well in memory.

Thank you in advance for your help.

Best regards,
