the "QUITE" tag in Cambridge Dictionary

This is indeed confusing, because the word itself has two contradictory meanings. If you scroll through the entire entry for quite, you will find them both:

B1. completely

A2. [UK] a little or a lot but not completely ([US] usually fairly, pretty)

Likewise, to consult their rivals at Oxford: quite

1. (British English) (not used with a negative) to some degree
   synonym fairly, pretty

2. to the greatest possible degree
   synonym completely, absolutely, entirely

In the Cambridge entry, they use quite to indicate the broad sense of to a moderately high level as opposed to its other, unrelated meaning of in a fair manner, or as they put it, in the right way. Under the entry from the Cambridge Academic Content Dictionary further down, they say to some degree instead of quite for this sense.

In American English, quite is quite strong; if my girlfriend is quite angry then she's very angry, maybe even extremely angry. In British and Australian usage, she might merely be reasonably angry or kind of angry. Unfortunately, beyond that you can only infer which sense is intended from context; there are no simple clues.
