Battery Pack Modeling - Self-Paced Online Course - Unable to Proceed Further due to Problem in Task 4 in the exercise "Exploring the Custom Battery Pack Block"

Hello, I have recently started learning about Battery Pack Modelling using Simulink/Simscape through the "Battery Pack Modelling" Self-Paced Online Course offered by MathWorks. I am taking the course through the Chrome Browser (Simulink Online) for the simulinkR2024b version.

Presently, I am facing an issue with Task 4 in the exercise "Exploring the Custom Battery Pack Block" under Section 2.1 - Pack Modelling, due to which my progress has come to a halt. The "Training Assessment" fails every time I click the submit button, despite following the instructions and completing the task.

To give a brief summary and clarify the context, in Task 4, we have to observe the battery voltages in the simulation. We have to start by right-clicking the batteryVoltage port of the Battery Pack and select Log Selected Signals. Next, we change the Stop Time in the Simulate section to 200, then click Run to execute the model. After the simulation is complete, access the Data Inspector from the Review Results section and select NewPack(8). A dialog box titled Multidimensional Signal appears. In the Multidimensional Signal dialog box, choose Convert to channels (24) and then select NewPack (1,1) and NewPack (10,1) to view the battery voltages.

Now the difficulty I encountered while performing the task is that after running the simulation and opening up Data Inspector from the Review Results section, I am not shown the option of NewPack(8) as mentioned in the instructions and instead shown NewPack:3 (8). Also, when I click and select NewPack:3 (8), I am not presented with the option of Convert to channels (24) and instead presented with Convert to channels (8). As a result, there are no options such as NewPack (1,1) and NewPack (10,1) to select in order to observe the battery voltages. I believe the "Training Assessment" fails when I click submit because I don't meet the criteria specified in the instructions. However, despite re-running the task multiple times, I consistently receive the same set of options to select, not the ones specified in the task instructions. Hence, I am unable to proceed further.

Could someone verify whether there are any problems with the assessment or the proposed solution?

I have attached screenshots for reference.

I experienced exactly the same thing, and because of that, I'm also struggling to complete the course.

I was able to duplicate the issue. I have reported this internally. There is not currently a workaround for this, but I would expect it to be fixed in the next update.
