Missing airspace

Hi Petr,
Could you tell me how to put back some airspace that recently vanished? I have checked many devices and all are missing it. This particular airspace still exists and is on charts. There may be more missing (worrying not to know if and where to check) but this particular bit is just below the Manchester UK TMA. In the past I have never noticed any errors at all....lots of flights and simulated flights to check my routes.
Could you explain the mechanics to how the FIF airspace is generated and is kept up to date...
Regards
