The blip in kudos calculation was probably caused by the fact that kudo is calculated periodically, with conservative assumptions between re-calculations.
One of the enlistments is broken, which is probably preventing them all from being updated. I'm not entirely sure what the problem is, but I suggest that you remove the enlistment and see whether the project fixes itself.
There is a discussion over at http://www.ohloh.net/forums/10/topics/2132 which may be relevant here.
Looks like sometimes a single auth error can hold up a whole lot of enlistments, so check that each is right and works from the command line.
Please note that the ohloh site is not a site for getting support about the individual projects it lists, you'll have to communicate directly with the project itself.
