Are these bugs or am I doing something wrong?

Using TMO and RSRD with patch1

Started my career and noticing a couple things here.

1. when I get a contact I can see it (planes only so far) I usually dive but tried staying on the surface for kicks.. As the contact gets close, the pre message that asks me what I want to do "dive to periscope depth, engage target and so on" After I click to continue orders, the contact disappears.. Thinking its gone some how, hit the Time Compression button.. Sure enough, I am attacked.. This happens everytime..

2.While sitting idle, I am losing fuel, not moving at all

3.My damage guys don't fix a thing.. I tried hitting battle stations, I tried moving crew around.. Nothing happens and they are not fixing a thing.

4.I seem to never run out of air, I am below the surface at max Time Compression and my c02 level never changes.

Thanks all
