[SignalTap-II] Signal colors Legend

Hello,

I tried to submit a service request on the site, but I kept getting an error (attached)

I kept trying back, and I keep seeing the error. My issue is as shown in the pictures attached. The pictures are snapshots from Signal Tap.

I understand that the red nodes are not found in the compiled design, but why?

On some of the red signals, I see a signal that makes sense and looks correct (see the attached picture). So, it appears it should be a "blue" signal..

On some other red signals, it just a static '1' or '0'. In some other simulations, however, I have been able to see these static red nodes dynamically changing, and the signals are correct. This behavior seems to come and go, and I would like to understand why. I need to be able to view all of these signals in Signal Tap.

I see that this issue was never really addressed. That is, only a simple explanation was offered for what the colors meant

I look forward to talking with someone from Altera about this issue and getting to the bottom of it.

Can someone help me create a service request for this issue?
