Multiple opening bridges.

Hi !
I am new to this server and I am from France.
I am experiencing interpretation problems with HEC-RAS v2.2 modelizing multiple
opening bridges.
I understand that the highest of all water surfaces inside bridges is the one to be
plotted on the longitudinal profile since only one curve can be plotted.
This confused me a bit at first. I tried to plot all curves together using a spreadsheet,
but it is remaining confusing : When looking at XS tables (bridge option), one can see
3 water surfaces (US, inside BR US, Inside BR DS). The US WS seems to have a
completely wild behavior towards the upstream common XS, where it is suppose to
connect.
All this is even difficult to explain, so here are HEC-RAS and Excel attached files for
who would be kind enough to help.

Files explanation :
Metric units used FYI.
Run program (subcritical) then select profile Q100.
Please also look at excel file. Aren't these weired profiles ?
