Change "Show next 7" to "Show recent 7" when at end of list?

I have 8 future meetings. While looking at our eight future meetings on:  bet.toastmastersclubs.org/clubs/10000003...gendas/?upcoming=all  I noticed that the text under the list of agendas correctly says “Showing next 7 of 8 future meetings.” There is also a button next to it that says “Show all 8 future meetings.”

When I click that button to display the 8th meeting, the button next to the list changes to “Show next 7.” Since there are no additional meetings to show—I have only created eight future meetings—the wording is a little confusing.

Would it be possible to change the button to “Show recent 7” when the user has reached the bottom of the list?

Changed button to say "Show First 7"

Thank you!
