Ok so no reply from the general cityfibre form, but my contact said he is unsure and will get back to me.
The author of the better internet dashboard also contacted me and said he is seeing same in another city, and he thinks it might be a glitch, I have gave him postcodes to check for main road (now unplanned) and side streets (all still planned).
Also tbb have their activated services plotter, no idea how accurate that is. There is a activated property on the other side of the park which is currently "unplanned".
