Issue with Multivalue Parameter resetting in Request Property(Version 9.2)

Hello Everyone,

I am encountering an issue with the Multivalue Parameter in the request property while using an Angular web portal (Version 9.2). When I select a value from the Multivalue field, it gets selected correctly. However, if I update another parameter, the value in the Multivalue parameter resets. This issue only occurs when I apply a filtering condition to the Multivalue parameter, which loads data from a table.

Could you please suggest an approach to handle this issue?

Thank you!
