Defect: Having multiple edit chords open before saving overwrites multiple cords

[hampster2018]

When a user clicks edit cord for 2 or more cords then edits one of them and clicks save, the cord overwrites other cords around it.

Steps to reproduce the behavior:

1. Go to 'Device Manager'
2. Add several cords
3. Edit 2 or more cords
4. Save 1 of the cords

The expected behavior is that when a user saves a cord it only affects the cord that a user clicked on.
