Query: Doesn't fit my vacuum

So I have an Oreck "Type B" handheld vacuum cleaner, which looks just like the vacuum cleaners that are labeled on the front of the packaging. However, the bag doesn't quite fit. I had to cut the cardboard around the opening and then use tape to make it stay in place. It looked like these bags would fit my vacuum for sure, but they don't.
