Zoho Assist Desktop.exe not terminating / leaving orphaned instances

Zoho Assist Desktop.exe not terminating / leaving orphaned instances

I am having an issue with the Zoho Assist Desktop.exe (64bit).  When the app launches it creates 4 Instances of Zoho Assist - Desktop.exe in Task Manager.  When I hit Close by "X" Out in the upper right corner, 2 of the instances are terminated but 2 instances remain.  Subsequent launches of the product create 4 more instances and orphan 2 of the instances on close.  

On a Busy workday I could have 4-10 orphaned instances of Zoho Assist - Desktop.exe in Task Manager, each chewing up memory and resources.  

Having to go into Task Manager to manually kill instances is time consuming.  I doubt this is "Working as Intended."

I have uninstalled, rebooted, re-installed clean.  Switched from 64 bit to 32 bit and back again.   The orphaned instances of Zoho Assist - Desktop.exe on close continue to be a problem.

Please advise.
