After upgrading to 4.7 from 4.6, one of the Blueprints in this user's project will not save its Replicates setting

One of the Child Blueprints in this user's project will not save its Replicates setting. The Blueprint (apa_room01) is a child of MasterRoom, which has Replicates enabled. When apa_room01 is first opened, this setting is disabled. Enabling it and closing/reopening the project will reset the property to disabled.

According to the user, this project was converted from 4.6.1, in which this did not occur. This does not occur with all children of the MasterRoom, just this one.

Tested in 4.7.2 binary and Main (//depot/UE4/Promotable-CL-2455917)

1. Open the user's project
2. Open the apa_room01 Blueprint
3. Enable Replicates
4. Compile/Save
5. Close/reopen the project
6. Open the apa_room01 Blueprint

Result:
The Replication setting is disabled.
