Integration Jira X Octane

Good afternoon everybody 

I'm trying to do an integration from Jira to Octane, our Jira is onprimises and our Octane SaaS, in this integration most of the fields mapped are to master, that is, it comes from Jira to Octane, however I have a single field in this integration which is from master i.e. it should go from Octane to Jira, everything from Jira is going to Octane, but Octane is not going to Jira, can you help me please, follow the step by step I did 

Step by step: 
1) Create a data source with access to Jira (On primes) 
2) Create a data source to access Octane (SaaS)
3) Create a connection in MF Connect between these 2 data sources mapping the following fields from story to type to Master ---->>>>

Jira                  Octane
My project ---->>>    My project
Summary ---->>>       name
Description ---->>>   description
Epico DEV ---->>>     Epico Dev 
Priority ---->>>      Priority
Status <<---->>>      Phase
Link Octane <<---->>> Link CHG


Put the connection to run, it runs and takes the stories from Jira to Octane, however when I change the Link CHG field in Octane, it doesn't change in Jira
