Polygon gets disappeared after extending another polygon

[Baby_1]

Hello,
I am going to design a RF board which needs to have a curvature in some tracks. As you can see I just do it by adding a polygon.
But after extending another polygon my past polygon which has different connected track name got disappeared. I am curious to know how to solve this problem?

I guess, it is about priorities - some polygons have higher priority than other (so altium knows which polygon should have the shape you draw and which is going to be cut off based on clearance). Have a look into Polygon manager: Tools -> Polygon Pours -> Polygon Manager. Polygons placed higher will have also higher priority. Try to reorder your polygons.
