Possible "bug" when using blank cues to trigger Comment Macros v.3.5.1

I was building a LOT of comment macro cuelists last night (blank cuelists - no information at all - just a comment macro) for another gentleman and I was having an issue with them not triggering. Everything was being done as virtual lists using the LISTS window on a Hedgehog.

I noticed I would push the virtual cuelist and nothing would happen. I would push the button a second time and it would fire. Upon investigation, I had inadvertently turned on "Add Release End Cue" to the stacks.

My train of thought (which could undoubtedly be wrong) is that this shouldn't have affected the lists triggering at all as a second push should "release" that cuelist and the first push should have triggered the macro (not that they needed to be released since there wasn't anything there).

I turned the option back to "Wrap around" and the lists would fire on the first press.

Could this possibly be a buried bug (since it happens very rarely with this situation)?
