Changing dynamic address-list to static

Hi, just wondering what I’m doing wrong here.

I have a few dynamic entries in ipv4 and ipv6 address list which I want to change to static.

I can do this for ipv6 address-list to change the entries to dynamic=no

/ipv6/firewall/address-list/set [find dynamic=yes] dynamic=no

But the similar command doesn’t work for ipv4 address list. Is there a different syntax here?

/ip/firewall/address-list/set [find dynamic=yes] dynamic=no

This is on RouterOS 7.5.
