Are you shure you did not unintentionally insert a Plugin, for example a linear phase EQ that causes latency on the system? This additional latency is NOT reported in the window you showed, there you only see the latency of the soundcard. I just tested it with the LP10 EQ which causes about 50-80msec latency but that window further showed 8.7ms latency.
In playback you will hardly notice it and may work a bit with the changed system but as soon as you start to do things live you notice the mess… My first aid in these cases: deactivate the plugs one by one.
Hope that helped a bit.
