“Reflection for port forwards”is unavailable

[sycada]

Hi,
    I encountered some problems in using opnsense(19.7.2).
    I've turned on 'Reflection for port forwards', but I still can't access the mapped address from the lan network.
    I've checked the forwarding rules, and these are all allowed.
    How should I solve this problem?

In port forwarding options ,I've tried to trun the NAT reflection "use system default" or "enable",Still unusable.
