Image upside down
Hi, this is a common "problem" for astronomical telescopes. Same with my Meade 3" refractor and spotter. It is actually a design 'feature' not broken.
The issue is that most astronomical telescopes naturally show images upside down, or some combination of upside down and left-right.
(Astronomers usually don't care, because space has no up or down.)
It is just the way optics work when lenses or mirrors bounce and bend light. (And since the professional astronomer wants the most light and most direct image, they usually don't want extra devices just to make it right-side up.)
Reason that binoculars don't do that , is they employ special internal prisms to get the image back right-side up.
Easiest solution for astronomical telescope is to buy what is called a "star-diagonal" or "image-erector prism". These will usually make the image look normal for us earth-based folks.
I do not know what exact type your Meade 227 telescope is, but the spotter scope is most likely a simple refractor. So it MAY be possible to install a star diagonal onto it. Or might not. Depends on the exact spotter scope design.
Another option may be able to buy a replacement spotter scope that is designed for correcting image orientation.
