0% in mean response% from Robyn_allocator result

Hi Robyn team, thanks for this amazing tool.

I tried to implement the code with the dataset you provided: dt_simulated_weekly and dt_prophet_holidays, with same hyperparameter settings and without calibration settings. As for the model, I selected one from Pareto-optimals, 5_277_3.

However, I noticed that in the allocation result, for Facebook_S, the mean response shows 0% despite the date range. You can see that in the first table, the date range is about 2 years, and in the second the date range is 4 weeks.

Here is the JSON file for Robyn_Model-5_277_3:
[RobynModel-5_277_3.json](https://github.com/user-attachments/files/18080319/RobynModel-5_277_3.json)

I'd appreciate it if there's any response on this issue.

ps.
