Analysis BI displays duplicate values in parameters

Content

This problem appeared on May 5th and disappeared with update 21B.
All Analysis BI in our production instance showed the same behavior.

We validated that the analyses had not been modified by any user.
Analyzing the problem we found that the problem was in the configuration of the Value Suppression. The correct value should be Suppress but the value it had was Repeat.

The same analyses BI worked correctly in our test environment and checking in detail we found that the configuration of the Value Suppression had the correct value which is Suppress.
These analyses were not modified by any user neither in production nor in test environment because nobody has the necessary permissions. Which makes us think that somehow they got misconfigured in production environment. Something important happened for all our BI analyses in the production environment.
