Failed Dependency Checks?

Hello again,

Since we've upgraded to Mon v1.1.0Pre1 dependency checks continually fail and all alerts for services that have any dependencies whatsoever are supressed.

Here's a slice of my config:

As far as I can tell, I'm doing what I should be doing. The dependencies worked before I upgraded. Any suggestions or ideas?
