Hi Jim,
I really appreciate you looking through my file so carefully! It's interesting to hear that you don't see any English titles. For me, the charts from rows 205-308 on the first sheet (Toutes les reponses...) are showing what is in the screenshot below. Somehow, all the charts on the other tabs updated just fine.
What is most perplexing to me about this is that the formulas for each chart are the same. The only difference is the cells referenced. In fact, I just kept copying the same two charts I started with and changed the cell references and colors. And when I started converting this from English to French, I changed all the cells they are referencing in exactly the same way, so I don't understand why some are updating and some are not. This is also not an isolated issue for me. It has happened multiple times on several different files as I've been creating these dashboards.
My default language is also set to US English, but I wouldn't think that would matter since it should be picking up whatever is in the cell the formula references, right?
Thanks again for your help!
