Can't say I've experienced so many of these anomalies or concerns with oil changes. Which is weird, they must actually be anomalies and not really concerns, because I've changed a schittload of oil.
You may not be concerned, and I agree they are anomalies. But look at numbers. In the time I had my 1693, I changed the oil in it at least 200 times, and there was a couple years it did not work. (When I bought it that Cat was in it's 3rd truck) Even my pickup has had about 60 changes. Looking at all the cars and trucks on the road, 0.01% of changes have problems is a lot of problems.
It's just something I do.
Drain oil (sometimes 2 min, sometimes 20), change filter.
Reinstall filter and drain plug (not necessarily in that order).
Dump the required amount of new oil down er throat and....done.
check for leaks Most times I change the filter while the oil is draining. On some it is easier to catch all the oil, and stay out of the oil, to get new filter on before pull the drain plug.
