One of the things I learned early on about Microsoft Project is that if you adjust the Calendar settings the Project Options dialog, you absolutely MUST change the schedule on the Project Calendar as well. Otherwise, the calendar and the settings become "out of sync" which can lead to needless confusion. The Hours per day setting is used in the Duration Equation in Microsoft Project. The Days per month setting is used to determine the Duration of a task in days if you manually type the Duration value in Months. In your situation where you entered 31 in the Days per month field, if you type 2 Months in the Duration column for a task, Microsoft Project will calculate a Duration of 62 working days for the task.
The main consequence of not changing the schedule shown on the Project Calendar is confusion as a result of Microsoft Project calculating values that make no sense. Trust me, you need to keep the options settings and the calendar schedule in sync. Hope this helps.
