Reflections in Post Process Settings will not package correctly

After packaging my UE5.4 BP project, the reflections are running at max intensity, quality and roughness despite being told to do otherwise by the level’s post process. The post process settings are 100% being applied to the project, confirmed by changing the min and max EVs during runtime for visual confirmation.

so far have tried:

Making a new project with post process then packaging (confirmed the issue is global)

DirectX 11

Deleting level post process to replace with player camera post process

Setting post process settings in blueprint during runtime (can change everything except reflections)

Everything to do with scalability settings

Making a new post process from scratch

works as it should in editor (both in viewport and Play mode)+ no error messages regarding post process in the packaging output log. I know its probably just a checkbox or two, would really appreciate if anyone could tell me which ones. so far has taken up 8+ hours of my life with no progress. only thing that’s truly stumped me in my 10months of learning. sry if i missed something obvious.

Also the average brightness seems to be up 25-50% (for example to achieve an EV of -5.5 it needs an EV of about -3.5), lighting is pre-computed even with force no precompute enabled and all light’s have their max draw distance reset to 0. not sure if its related to the reflections issue though plus haven’t looked too much into these issues yet.
