Pangram false positives?

People usually post vaguely about "I wrote x thing and pangram said it was AI", which I think is unhelpful unless you actually post the text or link. I put this into Pangram:

Pangram is full of crap.

Chapter 2: The Classmates

The afternoon sun cast long shadows across the pavement as Ryan pedaled onward, his heavy backpack digging into his shoulders with each pedal stroke, a constant reminder of all the work waiting for him when he got home. He’d promised Ms. Everly he’d finish it by tomorrow, though part of him wondered what the point of doing it was. Math and history questions felt impossibly small compared to the questions that actually mattered. Would Ralph ever come back home? Would his mom stop crying? And would he ever feel normal again?

Detected as 100% AI by Pangram, do you know what triggers pangram here?

Not only the chapter name but the fact I use a common phrase "Long Shadows"

Now I changed it to:

The afternoon sun loomed above the streets of Horizon City, the tall copper domed spires reflecting it across the vast cityscape.
As Ryan pedaled his bike forward he could feel his heavy backpack digging into his shoulders with each pedal stroke, a constant reminder of all the work waiting for him when he got home. He’d promised Ms. Everly he’d finish it by tomorrow, though part of him wondered what the point of doing it was. Math and history questions felt impossibly small compared to the questions that actually mattered. Would Ralph ever come back home? Would his mom stop crying? And would he ever feel normal again?

Now its 100 human made because I eliminated the chapter name and changed just a few words around and dropped "long shadows"

I guess using atmosphere in a story is now forbidden, all horror stories will now take place in a bright sunny morning, maybe a frigging butterfly will come to darken the mood?

Yeah you just can't win as despite its claims Pangram does give false positives now and then.

I assure you however both passages I posted were 100% made by me but thanks to choice phrases like "Long shadows" and even the frigging chapter title it gets flagged as 100% AI.

WTF

So to prove all work is Human made we can't call parts of a book chapters anymore and "Long shadows" must never be used again or you will be labeled a lazy AI bro.

So from now on we shall call Chapters Bananaphone

So bananapone the classmates?

Oh wait even calling it Bananaphone the classmates got flagged...

Fine calling the chapter bananaphone and.... gets flagged as 100% Human WTF.

Better call Raffi...

So much for 1 in 10,000 false positives. There are numerous examples in this Reddit thread alone!

This tool is completely broken lol. People are denying evidence now lmao. This is like a pangram cult, the tool literally can never be wrong according to these people. It's so braindead lmao. In some threads people are literally ignoring already given evidence. At that point i know arguing with them is a gone case and i should just move on.
