Indesign button triggers wrong animation

Application: InDesign 2018

Platform: MacOS Sierra

Sorry for the complex setup, but here's my best text description of my setup.

I have a slideout menu with several buttons.

1. ButtonA_Shape

2. ButtonB_Trigger (actual button)

3. ButtonB_Shape

4. ButtonB_Trigger

And then there's the actual Menu

When I click on ButtonA_Trigger it is set to do the following:

1. Run animation to show ButtonB_Trigger

2. Run animation to show ButtonB_Shape

3. Run Animation to show Menu

Now that the ButtonB buttons are showing and the menu is open, the following happens when I click on ButtonB_Trigger

1. REVERSE animation to show ButtonB_Trigger

2. REVERSE animation to show ButtonB_Shape

3. REVERSE Animation to show Menu

What's actually happening.

The first time I click on ButtonA_Trigger everything works (I've added fills to the _Triggers to confirm they are actually showing/hiding)

When I click on ButtonB_Trigger everything works, menu closes, buttons change.

When I click on ButtonA_Trigger AGAIN it replays the animation from ButtonB_Trigger!

And I have no idea where the issue is coming from. Thanks for any insight!
