This happens because PGFPlots only uses one "stack" per axis: You're stacking the second confidence interval on top of the first. The easiest way to fix this is probably to use the approach described in "Is there an easy way of using line thickness as error indicator in a plot?": After plotting the first confidence interval, stack the upper bound on top again, using stack dir=minus. That way, the stack will be reset to zero, and you can draw the second confidence interval in the same fashion as the first:

The content of the label nodes is determined by the argument to nodes near coords. It defaults to \pgfmathprintnumber{\pgfplotspointmeta}, so it uses the PGF number parser to format the numbers. By default, this rounds the values to two digits.
There are different ways to alter this. One is to set the optional argument to
nodes near coords={\pgfmathprintnumber[fixed zerofill, precision=5]{\pgfplotspointmeta}},
Or you could use the every node near coord style:
every node near coord/.append style={
/pgf/number format/fixed zerofill,
/pgf/number format/precision=5
}
Both will lead to the same result:
\documentclass{article}
