Likely the constitutions you purchased was for the grand lodge. The rules for the lodge are probably called bylaws and are likely to be only a few pages. The by laws should "state" when the monthly meeting(s) is (that's why it is called the "stated" meeting), plus when the annual elections are.
Notice that your right to vote starts the stated meeting after you pay your dues after you are raised. The votes will be for spending money, scheduling events, responding to requests as well as the annual vote for officers. Very many lodges vote to pay their bills, others give a chance to object with various wording.
For elections of lodge officers, I've seen a lot of them be unanimous. Perhaps there were some rapid fire words that you didn't know what they meant and then a gavel. I remember that happening a number of times as I gradually learned what happens in lodge meetings and what the words mean. "Say, what just happened?" Even with contested elections I've seen them happen in about two minutes. It is very unlikely they happened and you missed it, but it is within the realm of possibilities. More likely it was worked out at a committee meeting just before opening and the report of the committee was read in and gavelled on so fast it blurred by.
