Modifying the Opacity of the Event

[HieuLCM]

Hello,
I am utilizing the Phoenix framework to display the event in the Belle2 (GSoC 2023) project, and I am facing trouble when trying to modify the opacity of the event. Specifically, when modifying the opacity of an event, that event becomes covered by the outside detector component, even when it was not like that initially.

For example, in the case of LHCb:

Before modifying the opacity of Hits:

After modifying the opacity of Hits, the event seems to disappear.

When setting the opacity to the maximum to revert the modification, still nothing appears.

Hiding the covering component, we can see the event.

I wonder if this feature of Phoenix is intentional, and how can I revert the opacity modification (only by page refreshing)? Is it possible for me to change this feature, like still showing the event with opacity < 1.0 while displaying the outside detector component (opacity < 1)?

Thank you in advance.
