Hi Francesco,
Thanks for the report! We managed to reproduce the bug — luckily, it only happens in a very specific case and seems to affect just the visualization.
When you load a project with an input channel set to “All”, for some reason the display shows it as 1, even though it’s actually still set to “All”.
We’ve already prepared a fix for this, which will be included in the next update.
Thanks again for catching it and letting us know 🙂
