Why the glidescope disappears from the PFD during autoland?

[Billcoke 3]

In this video, the PFD captured the glidescope during descent, but why did the glidescope disappeared at frame 1:48 

Does this happens in the the real world?

Billcoke,

When you get the NO AUTOLAND, I notice that the ILS identifier on the PFD changes (even though the DME readout remains consistent). This is an indication that the NAV is now picking up a different ILS, thus preventing the system to continue on LAND 3. If you did not change your NAV1 frequency by accident at that time, I would then look at your installed sceneries around that airport for conflicting ILS frequency.

Out of curiosity, what airport is it (default or add-on) ?

This video is from another flight simmer. I encountered similar "No Autoland" for Heathrow RW27R, only happened once. couldn't replicate the problem again.
