Most times this kind of thing happens it is _not_ because the member states in questions want to "resist" the regulation or anything like that.

Instead it most times because they just failed to write down and pass a law, e.g. because they forgot, had to handle a pandemic, infighting not specific to the law dragging law making speed down and many similar issues.

One example I vaguely remember was when law makers wrote the country laws for some regulation they wanted to push _beyond_ what the regulation required in a bad way which lead to the law being prevented in one way or another again, and again, and again until the time period to put the regulation into local law was over...

So assumptions about countries being against a regulation, or "that they then shouldn't have voted for it" or similar can not be done without looking into the specifics of the country and regulation in question.
