Hi
In right side of the Excel page I see one error regarding Sales Line it helps if we know what was the error. But in general I found out
1) If page is in View and not Edit mode Edit in Excel sometimes does not work. I always make sure page is in Edit mode.
2) I realized filter (as you mentioned) sometimes does not perform well with Edit in Excel. I make sure to not filter the page. Interestingly if you use "Search" on top of page such as Item List then use Edit in Excel it works great.
