Mac of two buttons start the same

[Alwiz79]

I have 3 dash buttons here.
The MAC of two of them start with the same numbers/letters combination.
Like xx:yy:zz:11:22 and xx:yy:zz:33:44

Now, when setting up new instances in iobroker I am just required to enter the first 3 pairs of the mac adress.
What now? Since the first 3 pairs are not unique I'll probably have some problems here

Of course this is really common and happens very often, but this is not a problem for the adapter, because the gernerated devices are named by the full mac address. I know it's very confusing because you can give names for the mac familys, which seems to tell the user that he can name a specific button here.

Can you put a complete MAC? I have only one Dash-Button but he finds 7 devices.
