Stalingrad Bridges

[FLG]

I am playing a Stalingrad campaign as the axis and non of the engineers can damage a bridge. When ever I try it tells me the bridges are wired for demolition. But when I right click on the terrain hex it says there is a hv bridge but it doesn't have it WIRED. The same when I try moving onto a full hex bridge. When I commence bridge operations to wire it it says it already is, even the hex display doesn't show it to be wired.

When the Russians move next to a bridge you don't get the automatic attempt to blow the bridge. Is there no way to damage bridges in the scenario?

Glenn, I have btl file if you need one.
