Arturia Mellotron V sample region unusual behaviour

[teacue]

I have already reported this to Arturia support but I would like to know if someone else encounters the same behaviour.

I encounter an unusual behaviour in Mellotron V which is preproducible on my system:
Cubase 10 Pro - Windows 10 64 bit Arturia Mellotron V VST3.
1. Create a new project
2. Load Mellotron V
3. Create a new preset
4. Delete the default tape bank on the A track
5. Click Browse and load a custom sample.
6. Choose C# of the 6th octave on the Mellotron V keyboard as root note.
7. Try to change the range of the region to 3 semitones: from C to D with C# from the 6th octave as rootnote.
This is not possible, the region will always be automatically extended to five semitones if you insist to have this particular C# as root note.
This happens only for this note, anywhere else the programm behaves as expected.

Edit: after a systematic test I found out that it happens on several other notes too

For any one interested I got an answer from Arturia support.
They could reproduce the issue and will fix it with the next update.
