This is because certain fields on the task are set to "mandatory" using UI Policies. Since these fields are not visible on the visual task board, the user is not aware of filling out these fields and the "Save" action is not honored on the task, hence the new description either.
Ensure the mandatory fields are visible on the visual task board or disable the UI policies that makes them mandatory.
