What I can see is that an area with 36 vertices I located pretty much at the top and probably does not allow to read all the other lines. Can you make a picture of Plugin Status > MSAW View and how does those MSAW actually look like?

Other option is to draw an instrument approach safety area, which looks like a tie bow. Considering that your area is big it will certainly be lower than 1800 ft at some point.

Another option like I said would be to draw an instrument approach safety area to inhibit all the MSAW alerts. With circles it's a bit easier as you can gradually increase the altitude in case you actually want to see the warning if it's not safe.

Try to check if there are published coordinates for those on AIP charts (maybe they are georeferenced to get the coordinates). FINALAPP is not used in MSAW calculation - this is the setting from TopSkySTCA, used for exclusion of areas with parallel approaches and departures.
