SUMMARY
On the Windows self-contained Kdenlive, if I choose a network folder to render the project, it will create that folder on my main drive with the same name instead of rendering it to the network file.

If the path to render is
\\diskstation\Personal\Videos\render.mp4
It will be saved at
C:\Personal\Videos\render.mp4


STEPS TO REPRODUCE
1. Download the standalone windows kdenlive
2. Render a project to a network path
3. Check that same path on your main drive

OBSERVED RESULT
The output file will be saved to Windows's main drive

EXPECTED RESULT
The output file should be saved to the network path

SOFTWARE/OS VERSIONS
Windows: 10

ADDITIONAL INFORMATION
I have not tested this on the installable version.
