Budget Allocator - Solution X returns incorrect allocation

[DongHarry-Kang]

Hi When I run budget allocator, this returns an incorrect allocation; the budget for the two channels I used is around 50%; 50%, but somehow lightweight only gives 2% allocation to channel 0 and 98% channel 1. Can somebody provide any suggestion?

I had faced a similar issue. I solved it by changing the type of model, from "carryover" to "hill-adstock". The DR graphs from the carryover model were linear in my case, therefore the model attributed more and more budget to the media with higher slope. On updating the model to "hill-adstock", the graphs were relatively plateaued hence the allocation was correct then.
