@caneeraj, @hamayoon_amini2010, the temporary workaround for this is the following workflow:
When you are designing a new project:
- Design survey project (from form builder or upload an xlsform)
- Upload CSV file/media file
- Deploy
In cases where you simply wish to update your CSV file from an ongoing survey project:
- Delete the CSV file that is present in the server from SETTINGS>Media
- Update your CSV file and then upload the same back to the server
- Go to FORM>Edit
- Make no changes but simply press the SAVE button
- Redeploy
