Scramble not updating correctly in Custom Training mode

[patrykator]

Description:
In the CubeDesk application, while using the Custom Training mode, I encounter an issue where the scramble does change when switching to a new algorithm, but it updates to the scramble from the previous case instead of generating a new one. This results in the cube not reflecting the correct scramble for the current training algorithm.

Steps to reproduce:

1. Open the CubeDesk application.
2. Enter Custom Training mode and click Train -> Train all (you need at least 2 custom trainings).
3. Complete the training and switch to the next algorithm.
4. Observe that the scramble changes, but it reflects the scramble that was used for the previous algorithm.

Expected result:
The scramble should reset and generate a new scramble specific to the current algorithm when switching between them.

Actual result:
The scramble changes but matches the one used for the previous algorithm, leading to confusion during training.
