Its not an issue unique to P3D, as the lock ups and freezes around the Clacton VOR area have been reported by several FSX users (myself included) over the years. It IS a FTX Vector issue, and has been identified as being a specific 'water bgl' problem by member Gypsy Baron. I assume that not everyone is experiencing this, and coupled with the fact Vector updates are pretty infrequent at best, its highly likely to be addressed. The problem doesn't manifest on my PC when using UTX, but If you do a search for Clacton stutters, you'll find a few threads discussing the issue.

I have only the one region with the single option. All of the others (complete NA set) display two checkbox options.

I'm seeing pretty much what Scot is seeing (in FSX-SE), with a couple of exceptions. For example, In Scot's PNW Control panel, he only has the one checkbox option, whereas in mine, I have the two.
