1. Place HasReceivedEvent node in the tree
2. Create a variable
3. Try assigning the variable as Stored Value 1 inside the HasReceivedEvent
4. Notice you get the error.
5. Create another variable (make sure it's lower in the list)
6. Try assigning the first variables as Stored Value 1 inside the HasReceivedEvent
7. Notice it's successful.
8. Reorder the variables.
9. You can no longer use the first variable as an argument, but you can use the second one.

I just tried to reproduce it on my local version but wasn't able to and then tried it on the Asset Store version and was able to reproduce it. Can you send me a PM with your Unity version and I'll send you an updated version?
 
Thanks, Justin, the issue doesn't block my project, I just thought I'd share it here. Happy to hear it's fixed in the local version. :)
 
I find the same problem in SendEvent, actually. It is only the last/lowest variable, and if I re-order I can select it (and can't select whatever is the last/lowest then).

Using version 1.6.6
Unity Version 2020.1.9f1
 
I experience the exact same problem in Unity 2019.4.2f1 and Behavior Designer Version 1.6.7.
Both in the "Send Event" and "Has Received Event", whenever I try to attach a variable to the event I get the error.
When I create a second shared variable I am able to attach the first one, but it will never receive any data from the event.
I am surprised this bug exists already so long.
