The growth rate should be filled in; otherwise, the game will crash. However, at one point, 999 was considered a large number, but not all IDs have been used yet...

P.S. Let's use "you" from now on. ;)
So, for a creature to be selectable as a sworn enemy, the Ranger needs to destroy 2 weekly growth amounts of those creatures. Since "dummy" creatures have a growth rate of 0, 0*2=0. That is, there's nothing to destroy; they are already in the list from the beginning. To fix this problem, it's enough to give them a growth rate >0. It's strange that this bug hasn't been fixed yet.
