issue appears to be old.. yet it only presented itself on Update of Postman
v807 - duplicating a call DID work… now.. it does NOT.. and even the duplicate when made to be the SAME.. wont work…
Update seems to have regressed Postman - cuz all worked fine.. now Im in a FORUM instead of DEVing…
restarted app twice… then it worked… iffy,…but closing issue
Hey @ctoxyz
Not completely sure what issue you were opening, to close it. 
If you find yourself explaining what’s happening in the UI in front of you - Adding images and/or a quick video of the behaviour would allow others to know exactly what you’re trying to explain. 
lol… bane of my existence - issue issue issue post SOLUTION presents itself seconds later… leading to… “Dear Post, I sorry” lol
Unsure why the duplicate call stopped working… then did… PROB user err.
Sooo… until next Batime…
Thank you for tending to this 
SOLUTION : restart - re-save - re-look & re-apply
