Some rune pages I paid for are inaccessible after renaming/resorting in new client

I purchased all the extra rune pages. In the new client, I recently renamed some of the pages with very long names and also reordered the pages.

Now when I go to select some of the pages, they can't be selected. This happens in both champ select and in collection editing.

Interestingly, all pages show correctly and are usable in the old client, just not in the new one.

I tried renaming the pages in the old client, but this didn't affect the new client in any way.

I noticed that the old client allows one fewer characters in the page name than the new client and wonder if this has anything to do with what's happening.

When I choose one of the inaccessible pages, another page is selected instead.

In the collection editor, I'm able to see all page names correctly in the drop down box, even though I can't select some of them.

In champ select, the last 3 page names are identical and selecting any of them chooses a different page.

I uninstalled and reinstalled the client, but this made no change.

Any ideas on how to fix this?

Thanks
