I believe that you are seeing normal behavior. Protocols like GLBP are effective with sending traffic on the LAN side but have little ability to control how traffic is sent to you over the WAN links. Control of how traffic is sent to you over the WAN links is the responsibility of the remote router that is sending the traffic over the WAN.
This is normal. The GLBP protocol is a LAN-side protocol meant to enable load-balancing for hosts on a LAN which doesn't have a 'clue' about redundant paths.
To enable load balancing on the input of the wan-side, you'll have to either run a routing-protocol or have the sending side (the other sides) manually set static routes which enable the load balancing.
Based on what you have posted I believe there is not any sign of a problem. You have very close to a 60/40 split of traffic both inbound and outbound on these interfaces. It looks to me like GLBP is working as expected.
