Split Struct Pin on a Function output will return a compiler error

Split Struct Pin on a Function output will return a compiler error:

Error Pin New Param 1 X named NewParam1_X doesn't match any parameters of function NewFunction_0
Error Pin New Param 1 Z named NewParam1_Z doesn't match any parameters of function NewFunction_0
Error Pin New Param 1 Y named NewParam1_Y doesn't match any parameters of function NewFunction_0

1. Open any project
2. Open any Blueprint
3. Create a new Function
4. Give the Function a vector output
5. Right-click > Split Struct Pin on the vector output pin
6. In the Event Graph, attach the function to Event Begin Play
7. Compile

Results:
Compiler error:
"Error Pin New Param 1 X named NewParam1_X doesn't match any parameters of function NewFunction_0
Error Pin New Param 1 Z named NewParam1_Z doesn't match any parameters of function NewFunction_0
Error Pin New Param 1 Y named NewParam1_Y doesn't match any parameters of function NewFunction_0
