Hex with 2 bridges

[Tom_]

Playing the intro scenario and have captured Kotel'nikovdkiy.
I have moved my bridging unit into hex 12,14 (to the right of the victory point). The hex has 2 bridges.
I ordered the bridging unit to destroy bridge(s). It Destroyed one bridge and left the other intact. I would like the unit to try blow the other bridge but it only lets me repair the destroyed one.

Am I missing something or is this something that just ned to be fixed?

I'll look into it. Thanks,
Brian
