Might Excel have any "reset strange chart attributes"?

I have a chart in 365 that won't allow editing and points me to:

https://support.microsoft.com/en-us/office/make-sure-your-charts-are-web-ready-2063733d-f4ec-4869-8f02-1534ced82d78

... which I've done nothing to intentionally do anything listed, and have gone through the attributes of every chart element and can't see anything wrong (or "special").

Is there any option to "reset/adjust chart so 365 won't be so confused"?
