Reflection capture problem in VR Project

Hello, I’m currently working on a VR project, but I’m getting an error when I’m capturing reflections.

Version: 5.3.2
A good setting for VR projects such as forward shading, MSAAX4 and more

Specifically, I want to capture a reflection of a room. However, when I capture each reflection capture range in room 1 and room 2 (by scale adjustment), the object in room 2 can be seen illuminated in some objects in room 1 that do not seem to have anything to do with it.
Of course, each reflection capture range is independently separated without overlapping.

Also, when you place several reflection capture actors to give a reflection to a specific object by referring to the Unreal document, unwanted reflections come out. For example, one reflection actor in the living room, one reflection actor in the bathroom, and one reflection actor in front of the bathroom mirror were placed according to each range. However, when I captured the reflection, objects in the living room were reflected in the bathroom mirror.

Also, after building, I get a problem where the reflections and the reflections when I play the game appear differently.

Is there a problem with the project setting? Or is it the wrong way to do reflection capture? Or is there a bug in the Unreal version? I don’t know why.

It is impossible to attach photos due to the company’s security policy.

would greatly appreciate some help. Thank you
