Steps to reproduce
1. Create an automation with valueedge/octane to Tosca for Testcases and include test steps mapping as bidirectional
2. Create a test case with a couple of test steps in value edge and synchronize it over to Tosca
3. Validate the testcase in Tosca and add a new test step and checkin
4. Synchornize the change to Octane/valueedge
Expected
The newly added test step is appended to the existing test step
Actual
The newly added test step is overridding all the earlier steps
