Value Bets appear in Bulk and dissapear too fast

Hey there,
I just started with Starter subscription and it often happens that value bets appear in bulk (8-10 atonce) but dissapear so fast that you can, if your lucky, set 1-2 bets most times even null. How can I set those bets, why do they appear en gros / dissapear so fast. Thats pretty annoying. Maybe someone can help me with tis issue.

Thanx K.
