Wacky ILS approach in Flight Planner?

Does anyone else suffer from this issue, I upload my flight plan from Simbrief into MSFS, and then I choose my approach as ILS RWY 27R (in this example for EGLL), and then it sometimes (most of the time for most airports I’ve flown to) gives me some sort of weird wacky route into the airport, as shown below? I can’t edit it, and whenever I try and delete waypoints in the FMS it doesn’t do anything?
