2 way FSI using System coupling GUI

Dear Ansys users.
I am so excited about this new platform ( the first impression is awesome)
Well, I am working on a 3D fluid-structure interaction problem, my problem consist of a 3D twisted blade excited by air jets though a pipe of 8 mm diameter ( a step function of 1 bar amplitude) using a profile
The workbench is set to (transient + fluent) workstation as the parameters are as follow
---- Transient settings:
Â
for the fixed suppot:
System coupling interface
------- Fluent side
-------- SC parameters
Duration control: 2s
Step control:Â 0.0005 time step size
Coupling Interface: One set to fluent at blade_wall (System coupling region)
Two  set to transient system coupling region
Data transfer Dispolacement/force
Relaxation factor to 0.5
Convergence target 0.01
The questions- Â after finishing the simulation , I plot the displacement versus time at the tip of the blade
I was expecting a step, but the ramp at the edge, this I could not find reason why!!!!
The following was ploted from 1 way FSI using external data:
- Â The second issue, when I used system coupling GUI and launch the solution, the number of folvers set only to 1 which cause a big processing time even that I reset the values mannually to a higher solver numbers both in transient and fluent and the number of licences is available, yet the problem occurs
