Windows Ignoring Static Route

We have a network setup as follows.

Location A
ServerA (

Location B
ServerB (

There is a software VPN setup between these two gateways.  So from ServerA I can ping ServerB.  We're attempting to migrate the connection between the two locations to an MPLS connection.

MPLS RouterA -
MPLS RouterB -

So on ServerA I've added the following route:
route add mask metric 1 /p

And on ServerB:
route add mask metric 1 /p

The problem is....on ServerA just after I add the route....if I run a tracert to ServerB, the first hop is the static route and then next hop is immediately ServerB.  I do a route print after this and see that the server has automatically added a new route that uses a different gateway.

It doesn't do this on ServerB.  ServerB maintains the correct route and follows it.
Why is this route being automatically added?  How can I avoid it?
Is it adding this route because the default gateway is our main router and it has a VPN connection to LocationB (and thus, ServerB)?
