Heavily wrong estimated charging times Dacia Spring

As a car I selected Dacia Spring. As charging cables only Type 2. For some charging points I get realistic charging time estimations. (for 6.6kw on 22 kw ac chargers), but then oftentimes it seems more like he calculated with quick dc charging. Is this my fault or is the program buggy?

First 2 ok, last not. The ratio could also be vise versa.
