Cannot change the original casing used for parameter names

It appears that users cannot change the original casing used for parameter names after they have been set once.

1. Open the editor
2. Create a new blueprint
3. Create a new function
4. Add a new parameter
5. Change the name to "AbCd"
6. Press enter to set the new name
7. Change the name to "abcd"
8. Notice that the parameter name automatically returns to the casing that was used prior

Expected: The parameter name would be updated with the change in casing
Result: The parameter ignores casing and sets it back to was it was previously
