Potlatch2 - GPS traces now "broken"

Since using the editor in September & today, I notice my GPS traces have become “broken”… ie, it appears that the changes in direction are shown, but not the straight sections inbetween.
Is there an option to revert to a continuous trace, or a reason for this change ?

A mi tambien me pasa,por lo que he vuelto a editar con Potlatch 1.4 ,con el cual no ocurre
