how do i get ai bombers to actually bomb something in FMB?

A couple things. Make sure you are using attack area instead of attack target in your waypoints. The waypoint itself for attack area (the flashing icon) will be where you aim the bomb load.

If you are using the attack target waypoint, then you'll need to use the "set" command under the waypoint properties. This will draw a green line with a recticle in the middle. You'll need to attach that line to an actual target (red / blue object). Once that's done, you'll see the green line permanently in the FMB.

Last thing to remember is the AI bombers need to have time to calculate (believe it or not) their bomb drop, so you need a nice straight way point to the target for the last 60-75km. If you have them in the middle of a turn (waypoints too close together / not in a straight line) for the last 60-75km to target, they will not drop them. (no target solution)
