thank you for your great report. This is really helpful in tracking the issues.
Unfortunately I haven't been able to reproduce any of the issues; particularly the first and the second you describe are the most important. I can see that the underline of 4 or 8 parameters may be not present but I wouldn't worry about that since the parameters are remoted correctly, at least here.
Looks like a hardware roblem to me, particularly because even you haven't been able to consistently reproduce this.
I'll point out this thread and your description to our system engineer and check what he thinks.
all the best
