I've been having some issues with this plugin recently as well. They've been going for quite some time (not sure which update broke it, unfortunately), but I've finally gotten around to reporting it. It seems similar to what people here have been describing, but hopefully I can explain it more fully.
The plugin had been working for some time, to great success, when one day we started seeing this.

I thought I had more pictures (maybe more at the forums at the link in my sig).
Basically, the plugin sets everyone to the same class, just like it's configured to do. However, everyone spawns with the weapons (and I believe health) of their original class. They do keep the speed and animations of the forced new class, as you can see in these shots. So, if you were a Soldier, and SDMR makes everyone Scouts, you have 200 hp, a rocket launcher, shotgun, and shovel, and you run supremely fast.
This has been reportedly hilarious, but I think it's time that we try to find a solution. As I said, we have had this running properly in the past. We have the latest stable version of SM, and I've copied the offsets people have been discussing below (they seem to be right).
Code:
"Offsets"
{
"ForceRespawn"
{
"windows" "288"
"linux" "289"
}
}
