Heat shield able to decouple?

[mabarry3]

So, for some reason, I had a heat shield with a "decouple" option on it and added a second decoupler to my staging options even though only one actually existed. Decoupling it had no force (you can see the shield stay on top of my ship until the atmosphere took effect and it ended up moving), but what was odd was that it seemed to activate the actual decoupler below it too (the engine+tank moved away from the ship like they were actually decoupled with the 150 ejection force when I just hit decouple on the shield)

Is that normal or a bug?

Are you sure none of your mods add that functionality? I suspect it'd be a pretty simple Module Manager config.

The only mod I've downloaded any time recently was Protractor, which shouldn't have touched that function, and I have never had that option before, but I can check and see if any other mods could be messing with it (or if I see this again at all).

Try putting it on the other way around. Worked for me.

This is exactly what Deadly Reentry does. Are you sure you don't have at least the part file from that?
