Multiple Dots accessing single device?

[Jersey]

Hi,
I have 3 Echo Dots, but only one properly works my Schlage Connect Door Lock. The other two respond with , "please manually Lock ..."

Setup:
-using Hubitat Zwave as hub.
-Hubitate Skill: tried removing/reinstalling on Alexa account. Doesn't fix it.
-Hubitate: Excluded/Included the Schlage device. Doesn't fix it.

In all cases, only one (the same) Echo would successfully control the lock.

Any ideas?

Cheers
