Hehe .... everybody has got the answer in their posts but you're not aware you're doing it and making it worse
The pups see it as a game
so when you call them they are standing there and saying in their little pup minds .... Ready-Set-Go!
Come on Catch me WEEEEE!
and the more you call and the more you chase .... the more they will run
To make them come
You need to do it and train them when there are no distractions
in a calm but stern voice call them
and hold either a toy they love or a treat
when they come tell them what a good girl or boy they are
and repeat and repeat and repeat the process again and again
eventually they will think that good things will happen when you call their name
