I'm not sure there's any point in trying all that as the help agent I shared screen with was seeing the same thing on their end I think.  I mostly work in the Safari web interface but tried many other ways.

I already tried making a blank template for invoices and estimates and starting over, that didn't solve it.

I also tried from the phone app, did not solve it.  And tried clicking a link from my phone email into a phone browser, that didn't work either.

I tried opening it in a private browsing window in Chrome, still saw the wrong invoice.

I actually did try editing the template to put hours and rates in the description, clicked a share link and it did not show up, then moved it back to its own columns.  Did not show up.  Both worked inside my account to see the invoice and estimate properly, but not in the share link to clients.
