AEM Asset Hotspots Editor: Unable to change name

[demobuster]

Hi everyone

I added 3 hotspots for an image. Their names:

- Hotspot 1

- Hotspot 2

- Hotspot 3

Then I change name property for the first item to 'first'. When I open dropdown with items list I see that only the first letter was used and suddenly the last item gets the new name of the first one. 

It seems like a bug. 

We use AEM 6.5.6.

Any thoughts would be appriciated

Thanks in advance
