No worries, I think I know what it is: when I opened the query I got a compatibility warning; it seems I might be using an older version of Excel or Power Query, I thought mine is up-to-date. Attached is a shot of the query; there's no filtered icon on the Invoice Date column.

Cheers!

The filter icon is the drop down button on the column header. If you click on that you will have more filter options.

Yep, I  know. What I meant to say previously is I think the reason I couldn't tell that you filtered the column using the drop down button is because there was no filter icon on it after you filtered it; and maybe the reason it wasn't showing has to do with the compatibility warning. I've seen similar scenarios in the past when certain features in the editor don't show up after encountering the warning.

Thanks Mynda 

Oh, I see 🙂

No worries. By the way, I'd just like to compliment you on your content and all the work you do, it is simply awesome. 

Thanks for your kind words, Tyler 🙂
