Cannot generate valid invite with "Limit uses" set

I started a new, invite-only zone. I created a new invite with these settings:

Here is the result of pressing create:

Another user, not registered to the zone, copies and pastes the invite link and tries to join:

They are denied access because the invite code is invalid:

Here’s what I see in the invite status list:

This has happened for about five invite in a row. Am I using this wrong?

The invite works if I turn off the “limit uses” field. Is this some sort of weird browser pre-fetch behavior?

I first saw this on iOS Safari, but I’m also seeing it on Firefox 78.11.0esr

Setting the “Limit uses” box and putting any value in the number of uses creates an invalid invite.

Creating a time-limited invite works correctly.

Creating an invite not bound by use or time also works correctly.
