Multiple tasks are getting created for the same user input task in a process model

Question

Hi, 
 We are using Appian version 17.4. 
 On a click of button, multiple tasks are getting created for the same user input task in process model. We have the functionality of Save and Close button which on close will create a task under Tasks Tab which will open the same screen with previous saved data. 
 When on clicking the button, it creates two tasks under Tasks Tab per instance. 
 We are not able to find the root cause since this is happening only in one sub-process, rest are working fine. 
 Thanks and Regards

Hi Ravi can you try removing these nodes in this subprocess and reconfiguring them once again. 
 
Also, under monitor process, when you find 2 tasks for one node, if you right click over user input task node, and select the option x instances - whats the status are you able to find for both the instances? 
 
Also, I assume that there are no MNI configured. 
 
Hence try reconfiguring the same once again, hope that might help.
