We recently had an interesting issue occur and I wanted to see if anyone else has experienced this or might know of a way to stop it from occurring. We have a forms process with a variable "Requester_Email" however upon importing this process into Production this variable somehow became "Requester_Email_1" and processes got suspended because sending an email to "Requester_Email" failed. We checked both Staging and Instances from before the Import and there was no "Requester_Email_1" in Staging or on instances from before the import.
To get it working we added "Requested_Email_1" to the Send To on the Email Tasks and then exported the process so we could move it back into our Staging Environment.
Upon importing the Forms Process into Staging, we got a new variable "Requester_Email_1_1". The variable "Requester_Email_1" was still there, however more troubling is it seems "Requester_Email" was no longer a variable...
Note the missing email icon on the /Requester_Email entry. Validating the Imported Process gave "The name 'Email Requester' should not be shared by activity or events." and listed the email tasks with it.
I tried finding if anyone else had encountered this issue but a search which included "_1" was returning anything with a 1 in it.
Using Forms Version 10.4.5
