Blueprint macros with wildcard arrays fail to compile when nested

If a user makes a macro with a wild card array and then nests it inside of another macro. The wild card array will throw the following error. This can also happens with a StandardMacro like For Each Loop.

Error The type of Target Array is undetermined. Connect something to "Name of Second Macro" to imply a specific type.

1. Open the Editor
2. Create a new blueprint
3. Create a macro that uses a wild card array (See attached image EmptyArrayError1)
4. # Create a macro that uses the first macro (See attached image EmptyArrayError2)
5. Place the second macro inside of a function (See attached image EmptyArrayError3)
6. Hit compile
7. Notice the error that is given and that the "Length" node in the first macro is not receiving array information

Expected: The nested macros would receive array information
Result: Macro throws an error

Alternative repro

1. Open the Editor
2. Create a new blueprint
3. Create a macro that uses a wild card array, and connect it to "For Each Loop"
4. Call the new macro from the level blueprint -> the blueprint compile fails
5. Expanding "For Each Loop" macro makes the blueprint compile fine
