Brotformen or Dough Rising Baskets

Every time I use the brotform to raise bread, it sticks.  I don't care how much flour I put in it, it sticks!  What am I doing wrong?

If the dough tears when removing it, does it matter much? Will it rise again?  I am hung up on not "degassing" the dough when I get ready to form and bake.

Thank you
