Very little translation error

I know, it is a very small issue, but I want to report it anyway:

It concerns the Dutch language.

When I analyse files to cleanup in CCleaner I can choose afterwards Cleanup.

Then I get a popup what gives a warning and I can continue with Oké or Annuleren (in Dutch)

Oké must be Ok

CCleaner works very good in Windows 10.

What is the actual issue?

Should Oké be changed to OK?

In Dutch it should be Ok

Thanks, the developers read all threads, I'm sure they'll fix this.

What this person "Jaap Ton" says is (complete) nonsense: OK and Oké are both correct.

The (official) Dutch "Taalunie" (language authority) says: "Correct zijn oké en OK.".
