Strange behavior concerning Character Movement Network Replication and a Water Physics Volume.  Upon entering water volume, Character Movement mode is set to swimming, however if more than one client is connected, all clients will be affected by this movement mode, after jumping.  (regardless of whether they are in the water volume or not)

Steps to Reproduce

Download the attached project sample SwimmingBugProject.Zip

1. Open Project
2. In Multiplayer Options, set number of players to 2, and Run a dedicated Server.
3. Press PIE
4. Control Client 1 Player, navigate them into the water volume, notice their movement now behaves as swimming.
5.Control Client 2 Player, Jump in the Air.

Result: Upon landing, the Client 2 Player will also have their movement mode set to swimming, even though they are not in water volume.

Expected: Client 2 Player would have their movement mode unchanged.
