Weird bug? h2 to H2 tag shows md5 sum instead of text! Any security issues?

What weirdness is this? Should this be reported as a bug?
Instead of the paragraph text it is showing an md5. What the heck?
What typo or weird combo did I do in the tagging to cause this?

Is displaying this:

When it should look like this:

ABOUT OUR HIGHLY TRAINED GAME MASTERS AND FACILITATORS

All of our volunteer game mastes and facilitators undergo the most extensive training available in the role-playing game industry. Each GM trainee undergos a year-long training program toward each level of their training diploma. During their training, they begin helping with our community programs, under the guidance of higher-level supervisors and peer trainees. All of our volunteers undergo regular background checks. We train our game masters in a wide range of different game offerings to appeal to every age and play style. See the list below for the game offerings available at each level and the locations where they are available.

Here is the whole Markdown source to see if anyone can suggest what it is. Note that if I make both header tags capital H or both lower case H, issue goes away, only appears with mixed lower case opening tag and then uppper case closing tag. How weird is that?

I am guessing I messed up with some open or unclosed tag earlier in the page to cause this combo? Is this md5 number a security concern? is it revealing something it shouldn’t be? Or is it no biggie?

Please advise.

For quality control purposes we provide extensive training to all our Game Master (GM) volunteer trainees, which take quite some time to complete at each level of training (typically 1+ years per level).
This means that we have pecific offerings from different <a href="">game system tier rankings</a>.

The Level 1 Trained GM Game offerings are standardized trained games for quality control purposes and are generally available at all of our community physical locations as well as our online programs.

Additionally we are also constantly evaluating new games. Many of thse games that we are evaluating are only exclusively availabe at the RPG Center.
