No, that has nothing to do with the Safari extension. I've moved this to a new thread.
We've gotten a few reports of this but haven't been able to reproduce it ourselves.
What exact version of Safari are you running? Are you running any other Safari extensions or content blockers? (It looks like you have at least a couple.) Try disabling them.
To be clear, there is no mobile download page. This is the normal download page but something is removing the top part of the page.
The previous report we had was adblock-plus, which was seemingly running on the page even though they had marked zotero.org as whitelisted, and it was only resolved once they actually disabled it entirely.
