Hello, thank you for contacting us.

I see you are using only one variable to distinguish all discovery keys:

This is a very sensitive thing to do. Please add some additional {#SECOND.MACRO} to item prototype definition in it will work much better.

This is not really a bug. It's by design. If you have a lot of similar entities discovered you have to use more fields to make every entry unique.

I will close this incident for now as it is not really a bug but a configuration issue.

Kind regards, Aigars
