Event Not Showing Up In The "Select Event" dropdow

Hello,
When wanting to access the event's registrants for a workshop we have on June 2nd, I can't see the event in the list (from the "Select Event" dropdown.) I can see all of the other events we have in that dropdown. I can find the event if I search in the "Event" list by page.
Any thoughts? Thanks

Please disregard - there must be a limit to the list. Thanks

OK. Thanks Jim for the update
