High schools may have trouble finding teachers who are qualified to teach advanced subjects, also they may not have enough students to really justify a class at that level.

Whereas a Community College may have an easier time finding instructors, since there aren't licensing rules or a need to employ the instructor full-time. Also they draw from a wider student population so may not have as much difficulty filling a class.

One wonders about such teachers who have advanced masters degrees in education. Why are they not qualified to teach freshman college material?

A Masters degree is usually qualification to teach college in the field of the degree (regular faculty in community colleges, lecturers in major universities—though lecturers are somewhat rare).

A masters in education is qualification to teach education classes, not other subjects.

Someone with a masters in education may or may not have the knowledge required for a particular subject, say a math or science. Or another way, just because someone has a masters in education doesn’t mean they can teach any specific class. Their background could be in counseling, administration, school psychology, or education methodology... not, for instance, typical high school subjects.

A degree in anything but the subjects they teach? Does that mean that a high school physics teacher knows nothing more about physics than high school physics?

Probably not; the state policies adopted under the pressure of NCLB and it's successors put strong pressure on districts to hire teachers with at least a bachelor's degree in the field taught for secondary schools, and even teachers that don't will often have additional coursework as part of college breadth requirements.
