Unfortunately this is not easy to fix.  The problem is that the commands
for moving a paragraph forward and backward (which are used to determine
the extension of the paragraph to be filled) somewhat disagree in your
special case.  The command for moving a paragraph forward finds the
\caption macro and moves to its end because the macro is a so-called
paragraph command which should be put on a line of its own.  Then the
command for moving a paragraph backward finds the \label at the start of
the line and stops there because \label is a paragraph command as well
and at the start of the line it marks the start of a paragraph.  So the
paragraph to be filled only consists of the \label.

What you can do to work around this is to move the \label to the end of
the previous line, so that it is not at the start of the line anymore,
or to put the \label after the \caption macro on a line of its own.  The
latter option is the one AUCTeX uses when you insert an environment with
`C-c C-e'.
