There has been quite some confusion over the last couple of years about Bembridge's openness and closedness. At one point the freeholder blocked the runway to prevent movements while the future (and, I think, the liability insurance) were in doubt. Then, when it reopened there were, not surprisingly, some manning issues.
There was a period when you really had to phone to see if they were going to be open (NOTAMs or no NOTAMs.)
I imagine that there is still some confusion in the documentation trail.
