Total real work differs from individual real work summed in meeting

Hello,

On one of our project, I'm getting quite a strange comportement in real work count :



The meeting has been correctly created, assignment too, and real work entered for every resource. However, as you can see, the total real work is not equal to 0.5d but only 0.125d. Then the meeting can't be closed as there is still assigned work not consumed.

One other strange thing is that on the real work input table, the start date and end dates are not coherent (the meeting took place today 14 of June) :



However, I don't think the meeting has been badly defined :



Do you have any idea of what can be wrong and how to fix it ?

Thanks a lot !
