Add polygon error

[Tomasz_Barwinski]

If I draw a new area of ​​copper in a place where there is already an area of ​​copper, then unfortunately the new one sort of erases the old one - and shouldn’t the new one be separated from the old one?
Is a bug?

Are they different nets? Do they have different priority levels in zone properties?

Thank you ! - the problem was in the zone priority - it can’t be 0 and 1, it has to be 1 and 2.
