Mikrotik edit/set how to remove/reset a parameter?

Question

Mikrotik

Good day forum users. It was required to edit the firewall rules. Adding a rule through the console or changing the parameters of the problem did not arise in it. But I can't remove/reset the set parameter. For example, I scored dst-address=xxx.xxx.xxx.xxx and now I want it to be gone. Entered and set dst-address="" and space and just equal and disable. I still don't understand how to reset this value. On forums it is written to edit to change edit'om. no detail.

In the current version of the RouterOS firmware , the unset command is used to delete an element property :
Commands for the MikroTik console:

1. Go to the right section
   

   # Переходим в разде IP/Firewall/NAT
   /ip firewall nat

   
   
2. Removing a parameter from an element
   

   # Удаляем параметр "dst-address" для первого элемента в списке (номер 0):
   unset 0 dst-address

   
   

Everything is the same as above, but with one command: REMINDER just in case:
/ip firewall nat unset 0 dst-address

• View the list of commands available in this section:
  ?
  
• List the elements of the current section:
  print
  
• Set the value dst-addressfor the first element (number 0) while in section /ip firewall nat:
  set 0 dst-address=192.168.88.32
  
• Remove the value dst-addressfor the first element (number 0) while in any section:
  /ip firewall nat unset 0 dst-address
  
• Go to root partition:
  /

And what prevents you from deleting this rule and writing another one that is the same, but without this parameter?
