Mikrotik RB450G + Netgear managed switch

Hello, I recently purchased a RB450G and a Netgear managed switch. The netgear switch I bought supports the 802.3ad LACP. What I have done is taken ports 2-5 (four ports total) on the router made them apart of a bond

Flags: X - disabled, R - running 
 0  R name="Master" mtu=1500 mac-address=00:0C:42:53:FD:E7 arp=disabled 
      slaves=BOND1,BOND2,BOND3,BOND4 mode=802.3ad primary=none 
      link-monitoring=mii-type2 arp-interval=100ms arp-ip-targets=0.0.0.0 
      mii-interval=10ms down-delay=3ms up-delay=3ms lacp-rate=1sec 
      transmit-hash-policy=layer-2

and the first four ports on the switch and create a port-channel

(GSM7248) #show port-channel all

            Port-                  Link
Log.       Channel            Adm. Trap  STP           Mbr      Port    Port
Intf        Name        Link  Mode Mode  Mode   Type   Ports    Speed   Active
------ --------------- ------ ---- ---- ------ ------- ------ --------- ------
lag 1  CoreA           Up     En.  En.  En.    Dynamic 0/2    Auto      True
                                                       0/4    Auto      True
                                                       0/6    Auto      True
                                                       0/8    Auto      True

right now everything is working. However when I start my testing of the failover capability, the port does fail over to the other three, but if it comes back up, it will not be joined back into the bond unless I disable and reenable the BOND port.

Also, if i reboot the router for any reason, the BOND port will not work. I have to again, disable the bond port, and reenable it.

I've tried several small changes, i.e. changing the mii-type from 1-2 and back... I'm mostly curious if anybody have seen this problem before. and if so what their fix was.
