I found this bug for Helix Rack, for firmware versions 3.10, 3.11 and 3.15.
The 3.01 version works well, it seems like this error was introduced on 3.10.
Bug description:
If I change the effect type of some block (example: from Amp+Cab to Reverb)
When I change the type in the first column and then I click some of the options on the second column,
the first column change again to the previous type.
That's why you can see something like this, on where the first column has not relation with the others:
- First column: Amp+Cab
- Second column: Mono/Stereo/Legacy
- Third column: All the reverb effects (Dynamic Hall, Hot Springs...)
