Mwan3 always using first interface

Installing and Using OpenWrt Network and Wireless Configuration
1

I created 4 macVLAN devices and corresponding create 4 interfaces, then all of then got IPv4 address and connected to Internet,But when I configure it for load balance, all of them had same metric and weight,I'm expected it for every interface had 20% load but it always using first member of interface and load it 100%.

[root@OpenWrt:05:16 PM ~] # mwan3 policies
Current ipv4 policies:
balance:
 wan (100%)

Current ipv6 policies:
balance:
 unreachable

if I tried to adjust higher any member's metric, the mwan3 will shift load to first lowest metric as 100%.

These options should be removed from all interface sections. They may not cause trouble, but they don't belong here.

I don't see any other obvious mistakes, but the policy should look like this:

balance:
 vwan3 (20%)
 vwan2 (20%)
 ...
 wan (20%)

Have you tried rebooting the device?

Yes,I tried reboot and upgrade newer system, but all of them not working, finally I clear all datas and reconfigured it and works
