where did my dumplings go!

Hello


  I am fairly new to cooking, but I am either doing something wrong and 
don't have the technique down yet, but I have 4 qts of chicken broth 
boiling and I make dumplings according to the recipe on the Bisquick 
box, I spoon them in the boiling broth and about 20 minutes later I lost 
80% of them the broth is a white creamy style, what did I do wrong.

   thanks
   Chet
