"Remove Net Classes" during Update PCB?

[seba]

Hi all!
In PCB project I have defined net classes "AllPowers" in order to apply
25mil routing width rule for nets belongs to this class.

Then I go into schematics and try "Update PCB", and in "Engineering Change
Order" I have pozition "Remove Net Classes" and this is "Allpowers" net
class!
How can I prevent this?
