Pio positionning wrong

[Tiranus]

Hello

Here is my probleme (i'm french so i'll try to explain the best i can...)

On the map, all the colored points are misplaced in the way that they are all positionned incorrectly.

For exemple, they can be all on the left to the position they should be (i mean the real position on the background image of the map)

If i click on one spot, the yellow trail lead me to the correct position. But when i'm at this position, i'm well placed on the map but the spot is shown slightly to the left (one centimeter for exemple...)

Any idea ?

Tx.
