This may or may not be isolated to the H9 Control 1.5.1 release. When using More -> Rename preset list, I inadvertently typed in some "illegal" characters [other than A-Z', a-z', 0-9].
The resulting error message may be confusing to end users (especially those with a few terabytes of free space):
- Duplication failed!
- A duplicate of the preset list could not be created. Please check whether your device has any available disk space.
