DADman delay bug?

[JR Fountain]

Hoping I'm doing something wrong here but when I apply any amount of delay to a speaker in the control room section of DADman the signal cuts out, nothing passes through. Another observation is that when the delay is applied, some channels will change from a blue circle to a light blue circle, but others don't.

As I look at this more I am very confused about the patching in DADman. I have one 7.1.4 output configured and when I assign each speaker to a corresponding DA channel in the Monitor Profile the patches display differently in the patch bay. All have an "x" but some are light blue, some are dark blue and some are just the "x". Why?? The DA is not patched anywhere else in the patchbay. My expectation is that if there is no patching in the patchbay then all channels in my monitor path should just have the "x" and that's it. Is that right?

So confused. Thx for any help.
