I need help to get my balancing with mwan3 working

I'm trying to do a balancing with OpenWrt 23.05.0 x86x64. At first I had several problems installing the interfaces, but it worked out. Now with the mwan3 package installed I have made several configurations that I found on YouTube, but something doesn't add up, it doesn't work well, the main wan always consumes much more than the wanb. Can someone help me defect my configuration? Thanks in advance
