Sorry, I read your question wrong. You can disregard my last message.

What is the network type on the interfaces? I use "point-to-point" for /30's. Both sides need to be set to that way for that type to work properly. You may wish to try changing the type. The backup and designated router I believe are status statements for OSPF broadcast.

I know I've put at least three /30s on the same interface and I don't remember running into problems. When you're running OSPF on a /30 one router will always be the designated router and the other will be the backup - I don't think it normally matters which router has which role, but you can make it prefer one of the other by setting the interface priority.

    So I have this here mikrotik Ive been implementing ospf on
    Right now because this is transition, all MT ports hit the same switch
    Eth6 is on a /30 that is going to a powercode BMU thats
    distributing the default route, it works fine
    Eth2 is on a /30 that is going to a fortigate, it works fine

    the routes propagate as they should

    I initially tried to add another /30 to Eth2 for a second
    fortigate, but it wouldnt let me add the netwok
    so I put that /30 on eth3 it comes up in a state designated router

    I moved it to eth4, same thing designated router the other two
    that are working have said backup all along

    is there something about adding a third ospf interface to mikrotik
    i need to know here?
