SUMMARY
I created 2 small bash script to use as custom shortcut.  
I made sure they are executable and are owned by my user.
Then when i try to import them as custom shortcut, the first script gets imported, the second one does not appear, unless i delete the previous Custom Shortcut.

I tired both script in the same folder (user home) and also one in another subfolder.


STEPS TO REPRODUCE
1. create a bash script
2. make it executable
3. assign it to a global shortcut
4. make another script in the same folder
5. make it executable
6. assign it to a global shortcut


OBSERVED RESULT
no error, the same identical selection widow is shown and same buttons are clicked, but the second script does not appear in the list

EXPECTED RESULT
the script would be appear in the list
