I've got a route that tells me to turn right when it's clearly a left.

In the past, this was caused by there being two data points very close together, right at the intersection in question, and the actual turn seeming to GPSapp (on a very small scale) to be going the other way. This I can understand.

But in this case, we're talking about two data point that are exactly the same:

2774 -1955
2812 -1963
2812 -1963 HWY 49 NORTH
2821 -1927
2828 -1900

I'm told to turn right there, but it's a left. Is there any way to get GPSapp to ignore one of the two data points that are the same like that?

I know that either deleting the extra data point, or moving the turn instruction up to the first of the two data points, would correct the problem. But what about situations where I don't know that MapsOnUs has fed me this kind of data and it's in the player and it's now too late?
