address/address-set under nat destination

Hi everybody.

I; struggling to understand what is wrong with my conf.

I'm configurig a nat destination rule:

set security nat destination rule-set PFW-RASPI rule PFW-8080 match source-address-name ASET-YOTI-OFFICE

but when I commit:

root@SRX210# commit
[edit security nat destination rule-set PFW-RASPI rule PFW-8080 match]
'source-address-name ASET-YOTI-OFFICE'
Can not find address/address-set(ASET-YOTI-OFFICE) in default global address book
error: configuration check-out failed

However I have that address book configured

root@SRX210# show | display set | match ASET-YOTI-OFFICE
set security address-book YOTI-OFFICE address-set ASET-YOTI-OFFICE address YOTI-1
set security address-book YOTI-OFFICE address-set ASET-YOTI-OFFICE address YOTI-2

Question 1: What is the reason of that error?

Question 2: Why JunOS gives the opportunity  to restrict the access to a range of IP under NAT as well as under the security policy for that nat rule? What is the difference?

Thanks
