Bug: Poll Duration Always Resets to 2 Days

I've noticed a bug with polls created in forum threads that don't appear in the feeds.

No matter how many days I choose for the poll duration when creating it, the poll always ends after 2 days. The same thing happens if I edit the thread later and change the poll's ending time—it still resets to 2 days instead of using the value I selected.

I've tested this multiple times, and the result is always the same.

Could this be looked into?

Thanks!
