Yes, Dan, that beta mode feeling is certainly a good perspective to take, as it assumes that either the knowledge or the applications could be the problem. Whereby the knowledge in alpha or beta testing is often limited by the spare information one has gotten.
I never assume even today that the things I know are up-to-date, hence why I try it each and every time again – practically. Things, as you know, change. Then there is the idea of common practice and ideal practice. Also here, I never assume to know it all. In fact no one does, and only bullies would extrapolate from a short failure that the rest is equally flawed. To read through the (?) 3,000++ pages, assuming they where printed, isn’t everyone’s favorite work. Back in time, while the books where printed, I read them every few years cover to cover. Since then the amount has certainly grown and not shrunk.
Anyway, the magic is in the combination of all possible options, functions and tools, as well as objects. Which results in a nearly infinite number of possibility. No-One knows all of these, and certainly doesn’t go through all with each new release. So, I hope my little delay in finding the “cause” like in the above was fast enough. 
Thanks for your cooperation and patience.
Cheers.
