OneStream Pivot Grid Default Layout Works in Desktop Client but Not in Browser UX

I am using OneStream dashboards and have set up a pivot grid. On desktop, I have configured a default layout for the pivot grid, which works as expected. However, when I access the same dashboard through the browser UX, the default layout does not apply.

I have tried clearing the browser cache, but the issue persists. Has anyone encountered this issue before, or can provide insights into why the default layout is not being applied in the browser UX? 

Additionally, on Desktop, the pivot gris appears in classic format. On UX, it comes as a hierarchy. Can we default to use classic format on browser UX?
