Photoshop export

I upgraded to 3.3 and the "after export option" from Photoshop has a malfunction now.
When you select "Set to media player 1" the PSD-file is placed correct in Media Player 1
But when you select "Set to media player2" the PSD-file is placed in both mediaplayers 1 and 2. When you now try to replace another PSD-flie into media player 1 only: it replaces the existing files in both mediaplayers. How to correct this?

System specs:
Photoshop CS6 Windows
Atem 1M/E switcher
Atem 1M/E Broadcast panel

Are you sure you're not getting "Media Pool" and "Media Player" confused?

Your second step will require you to change the "Media Pool Location" to another slot in the Media Pool, otherwise you'll replace the image you previously assigned to Media Player 1.

I'm absolutely sure: I'm talking about the media player.
In the export-window in Photoshop the last option is: "After export". There are 3 possibility's:
1. Do nothing,
2. Set to Media Player 1
3. Set to Media Player 2

In the former software version this wasn't an issue. It worked correct!
