Hello,
Well, I am glad you're in a working state, but it's weird that the problem boiled down to using sequence structures - although they are not recommended when dataflow can be used to otherwise, they should not cause incorrect functionality in and of themselves. I'll take a look at all the code you posted again at least for internal exploration so that we can get the fundamental problem fixed if possible - as far as I understand, you removed all your multi-frame sequence structures and that fixed the problem.
Thank you for staying with this, and again, I'm glad you're over this rough spot!
Best Regards,
JLS
