How to configure Link Backup on TL-ER5120 V3

Hello everybody !
I have another problem yet, with link backup now...
I try to configure Link Backup on a router TL-ER5120...
I would like to when connection on WAN1 failed, WAN2 replace WAN1 !
I have searched on internet and forum, but I don't find the solution.
Here you can see the installation :
In a normal mode, the traffic is on WAN1 -> it's ok.
Now here is my configuration for link backup :
for online detection WAN 1 :
for online detection WAN 2 :
and for load balancing (I desactivate all... I don't want do use it) :
It works fine when I play with option connect/disconnect from WAN1&2 parameters.
Or if I physically connect/disconnect WAN 1 or 2
BUT :
if I lose the connection on the WAN 1, I want to say :
now the router doesn't switch on the port WAN 2.
I can see in the "Online detection" menu that WAN1 is well offline (and WAN 2 is online)
But I can't access internet.
If I go on the WAN 1 parameters and I click on disconnect button, so WAN 2 take the connection and I access internet.
I try to play with DNS off WAN ports, with parameters in online detection menu (specify IP or DNS lookup), but nothing works.
I despair, I don't understand why if I disconnect manually WAN 1 (with cable or with button in WAN parameters) it works !!!
And not automatically ????!!!!!
I hop you have an idea !!!
Thanks very much for your help !!!
