Hello Team,

We installed the **SlicerMorph extension** successfully (it shows up in Extension Manager), but the **Fast Model Align** module is not working properly.

- When we open the module, we only see the **Help & Acknowledgement tab**.

- The **Parameters tab** (where you normally select Fixed and Moving models) does not appear.

- We tried uninstalling and reinstalling SlicerMorph, restarting Slicer, and checking version compatibility, but the issue persists.

**Environment:**

- 3D Slicer version: 5.10.0

- Extension: SlicerMorph (latest build from Extension Manager)

- OS: [insert your OS here, e.g., Windows 11 / macOS / Linux]

**Problem:** Fast Model Align loads, but only shows Help text — no functional options.

Has anyone else experienced this issue? Is there a known fix or a specific build of SlicerMorph required for Fast Model Align to work with Slicer 5.10.0?

Thanks in advance for any guidance!
