T54PRO-ZE vs IPC-Color4M-TZ

I updated to the latest firmware (with AI-ISP disabled) and I got the same issue: as soon as the "Warm Light" is activated, everything goes to black after half a second (like if the camera was trying to under expose).
Anyone has any idea of what is happening ?
 
Maybe turn off the Overexposure toggle on the illumination tab?
 
I wouldn’t think it would change the exposure?
 
Ok I found the bug.
I noticed that the warm light is bright for around 0.5 seconds then it is switching to a much lower brightness (which is probably why the picture goes black as the exposure is set to the former brightness).
It is happening when I am changing the IVS rule, for instance for a different planning.
However if after changing the IVS rule, I visit (visit only, not changing anything) the Camera/Image/Illuminator settings (in my case for the night settings) and wait for the preview picture to appear, then the bug goes away.
Not sure if it goes away permanently, I'll have to check.
But at least I can confirm that this is a bug.

EDIT: unfortunately the "fix" did not survive the night. In fact it doesn't survive after 5-10 minutes. I reset all settings to default to see if the bug goes away, we'll see tonight.

More details about the bug: it is related to the working mode Day/Night.
In the middle of the night, I have half a second of the Night settings and then it is switching to the Day settings.
Which is why the light is going from bright to dim and why the exposure is going to under exposed.

Changing the exposure to "auto" in Day settings give me good exposure now in the Night time.

But what does motion look like with exposure at auto during the night?
 
Ok when I say "good exposure", it means that it is acceptable (not fully black). But I still have work to do to see what is the best combination to work around this bug.
The exposure is flickering between states for one second before settling down on the final exposure.
For just a glimpse, I have a very nice and bright exposure before it goes to the final "normal" exposure.
To avoid the flickering, I suppose I have to avoid the Day/Night working mode.

When the exposure is good, the motion looks good.
