e400 doesn't appear on dashboard after onboarding

Today i onboarded 4 devices:

* 2 x cn Pilot E400

* 1 ePMP Force 180 SM

* 1 ePMP Force 180 AP

Firstly, i' ve onboarded the 2 e400 devices and i had no problems. Everything was ok.

The same after onboarding the SM Force 180.

When i've onboarded the AP Force 180,i can't see 1 e400 on dashboard.

In the total number it is included. In the list of onboarded devices also. I can update it normally. But nowhere in the tree and when selecting it from somewhere the dashboard of the device doesn't appear.

I 've deleted and claimed it with S/N from cnMaestro. It's now OK.
