Reproduces in 10.2.2
Doesn't reproduce in 7.3.1

Repro steps:
1. Create an Enum keyword on a shadergraph
2. Drag the keyword onto the graph
3. In the internal inspector, switch the first and last entries of the enum
4. Rename the first entry of the enum

Expected result: the first entry on the node is renamed
Actual result: the first entry on the node disappears

Note: the reorderable list for the keyword at this point contains two entries with the same ID
