Update Statistics Button Missing - Imported Content

Please forgive me if this question has already been asked. I did a search and didn’t find any related question. I imported a short text from the internet and attached an audio file. When I save and open the lesson I am able to highlight words and Lingq them, but the updated statistics button the left side of the screen is grayed out and the update statistics button at the bottom of the page is missing. I don’t think I’ve reached my limit in vocabulary just yet. Any ideas why this might be happening? It has only happened so far with this lesson. All of my other lessons appear to have the button. Many thanks in advance for any help anyone can offer.

maybe you clicked by accident… that’s the only thing I can think of…

It does sound like you may have clicked the Update button by accident. Once clicked, it turns grey and can not be clicked again.
