Auto follow task when not requester

 Good afternoon folks,

I'm having an issue with a couple of my colleagues being automatically assigned 'follow' to tasks. Unfortunately the chap who set it up ha since left the company and we're trying to un-do this.

The flow for this is:

Client account manager sets up a task via the request button

Task then auto assigns 'follow' to two of my colleagues

I've tried checking in request forms and user groups to no avail.

I have access to the Owner of our Wrike account so can make any changes!

Cheers guys :)

Greg
