Hey there.
It's likely that it damage control team isn't doing anything because u have silent running engaged. To disengage silent running, u shud use the orders panel (buttons to the left on the screen) click the command room button and there will be a "rig for silent running" and "secure from silent running" key used to engage and disengage silent running. If I remember correctly, the z key will only engage silent running and does not disengage it.
Hope this helps
Gud luck
