I found this when going from a 7D (mark I) to the 5D3 - they must have some firmware in the charger that tries to detect non-Canon originals.
Oddly I have two identical third party batteries (bought at the same time) and the 5D4 is fine with one, but tells me the other is not original and asks if I want to proceed.
Just a case of waiting a bit and ordering some hopefully updated batteries (that have "cracked" Canon's latest detection algorithm).
Or...Canon could just go get F**ked!
Where do they get off deciding what brand of battery we should use?
Can you imagine buying a, for instance, FORD and then finding out it will only work with a FORD branded battery, and no third party equipment will work?
Or maybe, they do a deal with BP and you can't use any other brand of fuel?
