Apple-Dictionary gibberish in Pages on MacBook Pro

The Norwegian Apple-Dictionary is full of gibberish. When I write using pages, it suggests misspelled words, usually with random 'b's and 'g's floating randomly around the consonants. I didn't add these to my word-lists in pages, and my MacBook is brand new, so no one else could have done it either. It ruins my work flow, causing autocorrected misspellings to pop up randomly, forcing me to stop and baby-sit the program in case it decides to ruin my perfectly fine sentences the second I look away. Please fix it, or make pages more compatible with other spell-check providers, I'm begging you.

With tears,
