MapKit warnings and map Errors -Mismatching number of indices

Hi there, I am trying to develop a country guessing game using MapKit and GeoJSON data. I have verified that my data creates the outline of the country properly using other methods, but I run into an error where the map clips and does not show portions of the countries or islands when zooming at certain levels of the map. I receive the warnings in the terminal "Mismatching number of indices, indexCount: 30, triangulatedIndexCount: 27" and "Triangulator failed to fully triangulate polygon: (0.1296, 0.303328), (0.108053, 0.296605), (0.0671644, 0.289883), (0.0586311, 0.281121), (0.0397156, 0.27289), (0.0323911, 0.262393), (0.0610489, 0.260732), (0.102507, 0.284671), (0.140053, 0.292602), (0.133511, 0.291167), (0.137707, 0.293659), (0.138489, 0.29872)" I am not sure what these tuple values are, or how to fix the errors, as I have adjusted my data (removing duplicate coordinates, refreshing the map, etc). How am I able to counteract these warnings, or at least get a sense of what they are asking?
