Hi,
This is normal behavior when using destination address persistence. I guess that your VIP is with /32 mask and in that case you have only one destination. Thats why every time the persistence is choosing only one of your backend servers.
If you need persistence you can use source address or cookie based, but that depends on your network design. For example if you have a proxy before F5 and all the reqeusts are comming with the same IP address, the source address persistence will not work for you.
Have in mind that when you are using persistence it will affect the load balancing method. And even when you have round-robin, the traffic will be never equal on the backend servers.
