Level / Stage Blending Issue

[Bruce]

Hello guys,

The hitflash_red with alpha 1 in the darker level always shows red.
However when it comes to the brighter levels like the Desert level in the attachment, the hitflash_red color becomes orange!
I even removed all the FX's in the level, changed panel to background, and tried with different values, etc... but still not resolving the problem.
It also happens to some of other entities with alpha 1. Some of them are much harder to see (looks like invisible mode) in this Desert level.
Obviously, I didn't set up the levels correctly, is there a way to keep hitflash_red always be red regardless of how the level is setup?
Please see the attachments, thank you so much for your help.
