Problems with NAT/RULE
When i edit a NAT Rule, pfsense doesn't refresh, and the forward is not procesed properly, it is a bug ???, see image attached with pfsense version
You will have to provide far more detail than that.
No, it is probably not a bug.
For example I edit a rule that forwards the 8181 port to 80 with destination ip 192.168.2.20 then i change the port 8181 to 8282 and the destination ip to 192.168.2.21, and the rule never match, then if I remove the rule and create again works
