Conditional fields: Two file uploads

Hello

I use a dropdown menu where user can select if he wants to use upload field 1 or upload field 2 (both upload fields allow multiple files upload):
​


In the Events tab of the dropdown I use these events:
​



This works fine.

If the user selects Upload 1 then the file(s) get uploaded fine.
But if he selects Upload 2, the files don’t get uploaded.
Here are the settings of Action Upload 2:



Debugger:



As you can see, CF does use Upload 1 instead of upload 2.

If I disable Action for Upload 1, then Upload 2 works.
Even if I just change Action sort order (Action for Upload 2 is before Action for Upload 1) it works fine.

It looks like CF does not allow two Upload Actions if conditional fields are used?
Or do I miss a setting?

Any idea how to solve this?

Thanks a lot.
