Field Parameter does not remember Matrix Expand State

[jdusek92]

Hello,

Scenario:
I have a Matrix visual where the lower level in the row hierarchy is a static field. The top level is dynamic, controlled by a field parameter that includes an option for “No Detail”.

Problem:
When switching the parameter to “No Detail” and then back to a specific field, the Matrix does not retain the previous expand/collapse state. Instead of showing the hierarchy as expanded, it only displays the lower-level field, with no indication that a hierarchy exists.

see the recorded screen to understand:
