Thanks for the reply. I've checked everywhere. Even compared my game page to the support page and other game pages from my library.
See the comparisons here:

You might want to contact the itch support if you're not seeing it. I was able to access mine. I had the button on my page exactly like your first screenshot. You are looking at the right page.
They got me fixed up. Thanks for letting me know it was just me!
phew! glad to hear it :^)
